They sell these in one of the large, Ikea-ish stores, so Keitorin and I baked it , roasted the nuts, and added fresh strawberries from the fruit stand down the street. Stick 'em on with chocolate sauce, and it was an excellent, gluten-free way to celebrate the holidays! Especially since, in Japan, what you do on Christmas is eat Christmas cake ;)
