The Sugar Queen – Part 3 – Boiled Sugar…Finally!

So just the last two days of the Christmas event to cover and we’re done and dusted…is it just me or does Christmas seem a really, really long time ago? Where have those two weeks gone?

Anyway…day 5 dawned and there was no getting away from it for Adrian and Jorge…they would have to make a start on the boiled sugar working.
As a measure of caution, they decided to only cast one half of the figure, they weren’t sure if the sugar would come loose from the plaster when it had cooled and didn’t want to go the whole hog and create a huge sugar and plaster lump that they couldn’t pull apart. Both of them eschewed the instructions in the Platt recipe for casting sugar items to soak the mould in water before use as they reasoned there was still plenty of moisture in the plaster that hadn’t completely dried still…I very much suspect this was the root cause of what was to come, though as always hindsight is 20:20.

First job…boil some sugar into a syrup and then keep going until it is at the hard crack stage or thereabouts

The first sugar batch

It’s a lousy picture, but it really does do this attempt justice. As I have said several times before, the Tudor Kitchens at Hampton Court Palace in the winter are most definitely NOT the place to attempt sugar work, hell, even in the summer they’re less than ideal. As the sugar began to melt and the liquid bubbled…in the blink of an eye the whole lot crystallised and turned into a dry lump of junk, fit for nothing. The problem was the cold and damp…after a nice dry week, albeit a cold one, the weather had changed and warmed up enough for all the frost to turn to water and the fog of the day before had been washed away by a light but constant drizzle.
My suggestion for the second batch…pre-warm the skillet before putting the sugar and splash of water in; which they duly did and it seemed to do the trick, allowing the sugar to melt and start cooking away.

Pretty soon the whole mixture was boiling away nicely and after a few drop tests into some cold water both Adrian and Jorge decided to go for an initial casting

With Adrian taking the mould in hand, Jorge poured in the boiling sugar and with a combination of tilting and pouring the whole of the half of the mould was coated.

The first half coated in sugar

Showing admirable restraint, both Adrian and Jorge then left it alone for a few minutes rather than try to pull it out straight away and gave it a chance to harden off…in truth they were deep in conversation with the fascinated visitors to the Kitchen, explaining what it was they were doing and why, and fortunately not blaming me for the insanity of it all.
A few minutes passed and it was time to try to remove the sugar…

…it was however, stuck fast. Perhaps they hadn’t left it long enough? Perhaps some time would cause it to harden more…or soften in the damp atmosphere…or…???
It was at this point I left the sugar casting to catch up on some paperwork and knock out a tweet or two in the relative calm of the office. It was by now late in the day and I got into the ‘zone’ with some writing and lost track of the time. When I emerged from the office the Palace was closed and the Kitchen empty…I strode into the break room and scanned round looking for some semblance of a cast sugar figure, but saw nothing. Adrian looked at me with a look that spoke volumes and I walked into the break kitchen to put the kettle on. As I walked to the sink to fill the kettle I was greeted by this sight…

I guess it didn’t come out easily then

…the plaster mould soaking in the sink to try to dissolve the last of the boiled sugar! Neither time nor damp atmosphere had helped remove the bonded sugar and the only recourse had been to soak the whole thing in water to try to dissolve the bond between the two materials…or at least soften the sugar enough to finally pull it clear of the plaster. So much for tea…it was time for a beer and some thinking!

Day 6 – Go large then go home!

Day 5 had been New Years Eve, Adrian had a life and thus more interesting places to be…dancing the night away near Heathrow airport; a third of the team had gone home and the rest of us sat in front of one of the worst DVD’s I can recall ever watching, all of which meant there was little discussion about how to crack the casting problem that evening. Day six dawned and the new year brought new ideas to Adrian and he thought he’d cracked how to solve the sugar bonding to the plaster problem. unfortunately this idea meant completely abandoning the whole of the casting process as described and “solving” the problem by means of redesigning the whole process and mould material…in short, cast into a clay lined mould. As innovative as that might have been, and more of which shortly, solving the problem by throwing the whole thing away and inventing a new method wasn’t a solution. The end result, the cast figure, wasn’t as important as trying the process the correct way and then, not ignoring the parts that ‘don’t work’ or make no sense, but investigating the whole and complete process…just because we can’t make it work doesn’t mean the recipe/description is wrong after all, just that we are.
I will confess that at this point I lost a lot of interest in the sugarwork. Both Jorge and Adrian, though appreciating the idea that following the recipe as it was written was a good thing had gone off on one and were trying to come up with solutions to the problem rather than simply following the words…I went and concentrated on the roasting and the multi spit and got lost in the fire for a while

I returned from my funk just in time to see Jorge put the skillet down having just poured their final attempt using the plaster mould, though this time they had lightly greased the mould with oil before pouring.

Can you see the sugar?

A short wait for it to set and it was time for the moment of truth…

Heroic failure! A little longer and who knows what might have come out. Adrian was being a lot more positive than Jorge and his optimism was rewarded a short wait later as the remnants of what had solidified popped out of the mould with a deft pull

Wile the plaster attempt had been cooling they tried the clay lined version using the second mould

The clay lined mould

This was worse and they got no results from their ‘solution’…history was partially vindicated  😎

So was that it? No, not a chance. While all of the casting shenanigans had been going on, Elly and Tom had persevered with the press moulded sugar figure and worked on a base for her based on the Ditchley portrait of Elizabeth that had kick started the whole affair.

And with that, the sugar queen was complete…or as complete as she was going to get. A little bit of a brush and tidy up, a few more photos for the record and then this ephemeral object was gone, her job done.

Was it a successful project?…Yes, most definitely, thousands of people coming through the Kitchen saw the work progress over the course of the week and tens of thousands watched the trials and tribulations online via Twitter.
Could it have been improved?…Of course! I’m sure that both Adrian and Jorge and all the rest of the team that put something towards the sugar figures had the skill and abilities to not need to have been as cautious as they were when it came to the casting. I think that if they’d gone for the casting first, following the recipe, rather than staying safe and going for the press moulded figure then there may well have been a complete cast figure by the end of the week…though what was I saying earlier about hindsight?? The flip side to that would have been no press moulded figure for people to see early on through the week and it could all have kept failing as the final casting attempts did and we could have ended up with nothing at all to physically show after six days apart from two plaster moulds. Those are the choices that were made though and we ended up with a fantastic end product.

As always, I doff my cap to my more dexterous colleagues, as I said in a previous post, I just come up with the ideas, they’re the ones who actually make it all a physical reality for you all to see. Also we must not forget all those in the team who were working on other things over the week like the roasting, marchpane and comfit making…all of which I’ve ignored here, but are so important in order to bring the Kitchens to life and make everyone’s visit extra special.

A usual…comments gratefully received. There’ll be another short break before the next post on boiling in pewter vessels, and a new gallery of all the images from the event as I have a conference paper to write and present within the next week along with a mountain of paperwork and meetings, but keep an eye out on Twitter and here for the next blog update.

The Sugar Queen – part 2 – ̶C̶a̶s̶t̶i̶n̶g̶ ̶T̶h̶e̶ ̶S̶u̶g̶a̶r̶ – Errmm…Nope!

So, last time I went through the first couple of days of the Christmas event and detailed how the plaster of Paris mould was made ready for casting the sugar figure. The next stage of the plan was to follow the instructions in the Platt recipe for casting in plaster moulds and soak the mould in water; whilst this was happening there would be a little experimentation with boiling sugar and then about three-quarters of the way through day three the mould would be dried, put together, filled with boiling sugar and an attempt made at casting the first figure. Meanwhile, another part of the team would make a second mould from the wooden former in case things went awry with the casting in the first and it became unusable or broken in some way….well they were what I thought the plans were at least.
One of my major failings is that because I live with the planning for so much longer than the rest of the team I can never remember if I’ve passed on all the details to them, or if I just think I have! Posting a blog post with all the details in is one thing, but did I actually remember to tell all of the team these details? Either way, the result was the same and over the course of day 2 and through the evening it became clear that Adrian and Jorge had decided to forge another path. Yes a second mould would be made but there would be no casting with boiled sugar…worries and doubts had set in and they felt much more confident in trying to get a full, press moulded figure out made from sugar paste and then work up to the cast boiled sugar…so much for go large or go home!

The first thing they decided to do was make a second plaster mould, but this time they would use one half of the first mould to cast against rather than the clay. This meant the wooden figure was placed back into one half of the mould and then the whole exposed surface, wood and plaster, was then coated liberally with the tallow & oil mixture.

This was then coated in plaster exactly as before and when set, the original half was removed and the mould finished exactly as with the original…though in this case it contained a few more air bubbles than the first attempt and these needed to be filled with some putty consistency plaster after the fact

While Elly and Jorge were working on this, Adrian was working on some test pressings before steeling himself for a full on queen.

The sugar paste used was a rough and ready variation of the recipe from Ruscelli’s “The secrets of the reverend Maister Alexis of Piemont 1

all the ingredients were there, just not necessarily in the same order or quantities. Once made, and as Adrian started to fill the front half of the mould, it became clear that it would take an awful lot more paste to fill the entire mould…good job this was just a test. He decided to push the boat out…and push his luck, by trying for a complete front of the figure, and to make it a bit more flash, he used some of the marchpane that Zak had been making with various visitors, to give some colour and pizzaz to the face and hands. These parts of the mould were filled and then the rest had the standard sugar paste pressed into it at around 10-30 mm thick depending on both a) what was needed and b) what past was left, having started at the head and worked down. The results were pretty damn impressive, if a little flimsy…and this at least would give people the idea of what was being attempted.

With some more marchpane and sugar paste, Adrian finished off the day seeing how much material he was going to require to press out an entire figure

Once the mould was separated, the results were encouraging…even if it wasn’t the boiled sugar I had hoped for.

The test torso…not bad at all

…and so finished day 3.

Day 4

In an ideal world, day 4 would have seen the press moulding done and finished with nice and early and thence they would have moved on to the real deal, the boiled sugar. Unfortunately, it wasn’t to be so, only this time it was most definitely my fault! A previously booked and unchangeable appointment meant I would be away from the Kitchen for the bulk of the day, the instructions I left…under no circumstances do anything interesting or adventurous as there wouldn’t be anyone there to record it! I HAD to leave by 12.00 and absolutely no later in order to make the appointment, so anything interesting had to be done PDQ at the start of the day…Adrian did not disappoint!
First mission…paste…lots of sugar paste

After a change of hat and Adrian starts churning out sugar paste

Once the paste was made, it was simply a case of packing it into the plaster mould

and then closing the two halves together…with some vigour

From this point on things got a bit…well, physical, with an awful lot of grunting and groaning from Adrian as he tried to force more paste into the mould so that all the detail was filled and there was sufficient wall thickness for the whole to not sag and droop when it was finished.

Rolling out paste for a base

It turned out that without a solid base though there was little chance of the figure standing upright upon removal from the mould, so Adrian made a base out of a hastily made batch of paste and used this to seal the bottom of the skirts, the void now being packed full of flour to hold her steady when she was complete.

All it took then was a little bit of fiddling and the first half of the mould popped off a treat. This meant Adrian could do a quick tidy up around the join while the figure was still supported by the back half of the mould as he wanted to avoid excessive amounts of handling until the paste had hardened a little

The torso came loose from both halves of the mould at first, which caused me a little concern that the back of the figure may have been incomplete or broken…something I need not have worried about

Then with the deft hand of a master…as well as a little shaking, cajoling and a healthy dose of luck, out popped the Sugar Queen!

I think the voice of the child watching from Adrian’s elbow said it all…”Oh my God! Wow!”

Free at last!

By now it was 12.30…and I was VERY late!
As I sprinted out of the Kitchen my parting words were once again…”Don’t do anything interesting!” and with that I was away for the afternoon. So what did I find on my return? Turns out they’d been quite busy…

A pair of press moulded sugar queens in sugar paste and marchpane

Marchpane and sugar paste figure

…and that’s how day 4 finished.

Had they chosen to, the surface of the figures could have been smoothed out quite a bit before the paste set and that would have removed all of the cracks and imperfections, but to be honest, I don’t think anyone cared. They’d managed to get two fairly impressively large figures made and run through the process in front of a couple of thousand visitors plus several thousand more online…they deserved a beer…or two!

Next post…the last two days of the event and finally some boiled sugar casting!

As always, comments gratefully received, and once again, some of the images will expand to a larger size if you click on them, so give that a go if you want to see some more detail.

The Sugar Queen – Mould Making

So the equipment is cleaned and put away, the team returned to their homes and the dust has settled on another Christmas of cookery at Hampton Court Palace…but what did we achieve?

Two posts ago, <HERE> , I detailed the plans for the work over the week and gave a little insight into the methods that would be applied to making a cast sugar figure in front of our visitors. Those who follow on Twitter will already have seen most of the results but, free of the 140 character limit of tweeting, I can flesh all that out for you here and lay bare the highs and lows for those who eschew Twitter.

So the plan was a simple one, we would make a wooden former, we’d make a mould from that former, we’d cast a positive in sugar from that mould, and Robert is your mother’s brother…we’d bask in adulation and glory! As always through this, when I say ‘we’ I mean ‘the team’ and then, mostly not me…I come up with the stupid plans and can manage the donkey work when called upon, the skilled work needed for this insane idea was all due to the rest of my extremely handy and talented colleagues.

The wooden former from the front
The wooden former from the side

Contrary to his Davros related text message, Adrian turned up with a cracking wooden model to be used as a former for creating the mould with. Apparently she’s a little lopsided, but only Adrian noticed that…it irks him because he made it and it wasn’t “as good as it should be” but I’m damned if anyone else noticed…even when he pointed it out to us.
The plan of action was : Day 1, coat the wooden former in wax to seal it and then get this ready for casting. Day 2, construct the casting box, line with wax/oiled paper and begin the casting process with plaster of Paris. Taking the resultant mould and leaving it somewhere nice and warm to dry overnight (shouldn’t be a problem, everyone at HCP seems to like having their office at volcano like temperatures 😉 ). Day 3, investigate boiling sugar and spend the day making sugar paste 1 as practice for … Day 4, cast the first attempt in boiled sugar; trying as many times as possible through the day…continue this for the rest of the week. Simultaneously,  from Day 3 on, make a second mould with which to make press moulded sugar paste figures with and to use as a backup when we inevitably took things too far with the first mould and ended up with an irreparable kit of parts.

Day 1

Day 1 started with a bit of a shock…ice and frost! We were expecting things to be less than conducive to confectionery work in the Great Kitchen, after all there’s a reason that the original confectionery area was above the pastry department…it’s large ovens meaning that the rooms above would remain warm and dry, unlike our Kitchen which is cold and damp, I suppose at least now it was just cold and much less damp than usual.
First task, seal the wooden former, so Jorge fired up the portable stove while Adrian got some beeswax from the store cupboard and threw it into a skillet to melt.

Once the charcoal was up to temperature, the wax filled skillet was placed on top and left until the wax had all melted. At this point, Adrian ladled it over the former until it was mostly covered and he then began the rather laborious task of smoothing the lumpy wax out so that the wood was evenly covered and sealed for plaster casting.

Clearly it would have been so much simpler to just have a deeper pot and more wax allowing the former to be dipped into this to coat it in one go, but unfortunately we a) didn’t have enough wax to do this, b) didn’t have a suitable pot that both wax and former would adequately fit into and, most importantly c) We aren’t allowed to do that sort of thing…and a damn good job too! Our key Principle at Historic Royal Palaces is Guardianship…

“We exist for tomorrow, not just for yesterday. Our job is to give these palaces a future as valuable as their past. We know how precious they and their contents are, and we aim to conserve them to the standard they deserve: the best.”

We are extremely lucky in being able to cook, experiment and experience life within the Kitchen at Hampton Court as close as it is possible to  in the ways these things were done in the past, there are limitations though and these are there to ensure that the building is still there for future generations to come…and not coated in beeswax by a bunch of cretins playing with a mad idea!…but I digress (as usual).

Day 2

By the morning of day 2, Adrian and Jorge had completely rethought how they wanted to make the plaster mould. Rather than make a mould box and create a large two piece mould that was essentially a cube in shape with the hollow of the figure in the middle, they wanted to use thicker plaster to cast a more organic mould off of the wooden figure and without using a casting box. Admittedly this would save a lot of time that would have been spent making the box and would end up using much less plaster…a win all round. All that would be needed would be to divide the wooden former into two halves with some clay, create a fence of clay around the bottom of the figure

and then slap on some thick plaster. Once side one was dry, the clay could be removed and a second coating of plaster on the un-moulded side applied to create a complete two-part mould.

Of course, things aren’t ever going to be that simple, and wax or not, the former still needed a coating of a mould release/grease to ensure that it slipped from the plaster when it had set. This was made of a mixture of tallow and oil, heated together over the charcoal and then liberally applied to the former and clay surfaces that would be coated in the plaster. Once this had been applied and all was cleared and ready to go, Adrian and Jorge mixed the plaster up to a consistency of raw meringue and began to liberally apply it to create the first half of the mould.

The first half of the mould made

The plaster didn’t take too long to harden to a degree that meant Adrian wasn’t forced to hold it in his hands all afternoon and they were left with half a mould curing in the Kitchen. Once this was set sufficiently the clay could be peeled off and the plaster tidied up a little where it had formed areas that would allow the back half of the mould to lock to the front with no chance of separation.

Once this process was complete a clay fence could be added to the base of the rear of the former, and another liberal coating of the grease mixture applied all round before coating with more plaster.

Once the final coat of plaster had been applied, and as you can see from the videos, the consistency was fairly varied meaning that there was quite a difference in the amount of water in the batches and thus quite a difference in drying time, the whole affair was left to cure for a while until it was solid enough to move on.

The completed mould curing

Once a suitable length of time had elapsed…calculated in tea breaks and trips to warm up in the break room; it’s not often you can be thankful for an exothermic reaction like plaster curing to keep you warm in a cold kitchen 2 …it was time to take the leap and crack the mould open!
First step was to trim the edges with a knife to make sure all of the splashes and any plaster overlap that still remained between the two halves was finally removed.

Then with a little bit of coaxing, the rear portion of the mould popped off…

The rear half of the mould

Then with a little more wiggling and jiggling…and a few muttered words

The former was free and we had two halves of a mould ready to go!

The front half of the plaster mould

All that was left was to do a quick test press with some sugar paste to check that the figure would be visible

then it was off to a warm, dry place overnight to dry  and fully cure.

Whilst typing this it has become very clear that there is no chance of me being able to write a single post that covers the whole of the week’s confectionery capers…not if I want you to not die of boredom whilst reading it at least. So consider this the first post, with more to come when I’ve typed it all up and had a little family time to myself; I’ll also add a gallery of all the images that I took over the week, but again, that’ll have to wait a few days. For now it’s worth noting that some of the images in the post will expand to larger size if you click on them…might make some of the detail a little clearer for you.

As always, comments gratefully received…positive, negative, ambivalent…and keep an eye out for the next part some time early next week.

  2. Yes, I am well aware of the dangers and damage that the heat from curing plaster can cause. A full risk assessment was carried out and the plaster work was carried out as safely as is possible to do so. No hands or other appendages were kept in wet plaster as it cured, only the outside of the mould was held and then only for very short lengths of time
