Hollow 3D Figures

While I didn't pursue a professional chocolatier program until 2018, my first introduction to chocolate making came while I was around ten or eleven years old and part of a Girl Guide troop. One Wednesday night, we gathered in the basement of the Salvation Army temple and our troop's leader demonstrated how to make various solid and filled bonbons. Of course, she was using Wilton candy melts (compound chocolate) instead of "real" chocolate, so there was no tempering involved, but we learned processes for shelling, filling, and capping. I remember the chocolate being kept warm with an electric skillet, the molds being painstakingly painted with a Testors paint brush (the kind you use on model cars), and the can of condensed milk that had been transformed into caramel by boiling it. I was hooked. And my dear parents indulged my interest, taking me to the religious book and bible shop in the mall, which for some reason was the place to buy candy melts and molds. 

I've come a long way since then. But every now and then I think back to one of the techniques she talked about that night -- creating hollow 3D figures. She described two-part molds that snapped together. You would pour some chocolate in one piece, snap them together, and then rotate to coat the mold until the chocolate solidified. It sounded easy enough, and at some point I used my allowance to buy a 3D Christmas tree and a 3D Santa mold, but I never tried it.

While hollow 3D figures wasn't part of my professional chocolatier program, as I engaged in research for various assignments, I stumbled upon videos demonstrating how 3D molds are used in factories. Instead of clipping or snapping together, the molds are now commonly held together with magnets. And instead of a person rotating them by hand, they are placed on a machine that slowly rotates in multiple directions. Smaller, artisanal shops may have 3D molds that aren't fully enclosed when clipped together. They fill them with chocolate, let them sit for a few minutes, and then pour out the excess chocolate to leave a hollow figure. 

The production, of course, is a little different if you want to have a surprise in the centre of the hollow figure, like M&Ms or Smarties. Anyone who's made hot chocolate bombs knows this process: mold the two pieces separately, add your fillings to one side, and then attach the other half either by melting it a little on a hot pan or by "gluing" it into place with more chocolate. I've made cocoa bombs before, including some Grinch-inspired ones with a friend -- but I've never made a one-piece, hollow chocolate figure. Until now. 

This week, on chocolate night, I decided to try it. I have a few egg molds that can be combined for this purpose. I grabbed some white chocolate left over from Christmas, prepared it using the direct tempering method, and poured it into one half of the mold. With binder clips, I secured the other half and began rotating. Once I was confident the chocolate was well distributed, I let it sit for a minute and then flipped it over and let it sit for another minute. Then I tossed it in the fridge to set. Fifteen minutes later, I pulled it out and was saddened to find I couldn't unmold it. I thought perhaps I'd messed up the temper. I made the mistake of using too much force and I cracked the egg in half. Still unable to get the chocolate out, I put it in the freezer for 5 minutes and the two halves then popped out cleanly. The next day, it was clear that the chocolate had been in perfect temper, but I had been too impatient. So I tried again.

My second attempt was with leftover dark chocolate. I repeated the process, but this time when I took it out of the fridge, instead of trying to unmold it, I popped it into the freezer immediately for a quick cold "shock." And the hollow egg unmolded perfectly! Huzzah!

Pleased as punch, I set it aside on a crumpled paper towel so that it wouldn't roll around. And then I turned my attention to "fixing" the white chocolate one. I could have melted down the chocolate and molded the egg again, but instead I decided to put a surprise inside. I took the first half of the egg and smoothed the edge by melting it on a hot frying pan. Then I filled it with candy before smoothing the second half and applying that on top while the chocolate was still melted. I patched the bottom with a little melted chocolate. Voila! Done. 

I'm very excited with how these turned out and for the possibilities going forward. The only challenge I have now is that the foil I usually wrap chocolates in isn't big enough for this jumbo Easter egg. Consequently, I'm going to need a creative packaging solution. But there's plenty of time to sort that out by Easter.
