What is Siberia cake?
This cake always features the same ingredients: yokan and castella. Yokan (羊羹) has a jelly texture, but it’s vegan: instead of gelatin, it is made of agar, red bean paste, and sugar. Castella is a kind of sponge cake, inspired by the Portuguese cuisine. You can find many different variations of flavours: matcha , chocolate, brown sugar, and even cheese. Unchanged is the soft, moist texture of the cake. It is a remarkable old-fashioned cake. In the early Showa era, between approximately 1926 and 1960, Siberia cake was the favorite dessert among kids. Then it gave way to more elaborate, European-style cakes. Some people say Siberia cake became popular again after Hayao Miyazaki depicted it in his anime “The Wind Rises”.
