Our supper club is jewel-themed this month, and I'm dessert. I'm devoid of inspiration for some reason, so would love to hear any ideas of jewel or bijoux-themed desserts. Broadly applicable is fine - we once did a dinner themed "speed bump" and we made black-and-white cookies for dessert (speed bump = sleeping policeman = black-and-whites, get it?)
Anyway, I can get past making something ru-barb-y red. And I may end up doing that, but welcome alternative suggestions!
