I swear that was more difficult than being told what he wanted.
After many hours scouring the cupboards and looking at cake photos online for inspiration, I came up with a large geode.
Most geode cakes online are, frankly, weird—an ordinary tiered cake covered smoothy in fondant, with a slash down the side filled with geode crystals. They don’t look like a geode at all, and some look disturbingly like vaginas. I didn’t think my son would appreciate that. I strove for a more natural geode look.
I also hoped for a tastier geode material. I was inspired to do a geode by a bag of crystalised ginger in the cupboard. Most geode cakes, though, are made with rock candy, which isn’t the nicest accompaniment to cake. On a spice cake, I thought crystalised ginger would be a much more appropriate flavour (and texture). Unfortunately, my experiments with colouring ginger were uninspiring—the ginger had a beautiful sparkling appearance, but light colours looked grey on the yellowish ginger, and dark colours looked black. I couldn’t manage a nice geode-like lavender.
So I made purple hard candy and broke it into shards for the crystals.
The result was reasonably geode-like, and easy to make. And better than a crystal vagina.
