Known as a traditional Japanese confection Wagashi, “Castella (カステラ)” is a fluffy sponge cake made from hen’s egg, wheat flour, sugar, and starch syrup.

As for the origin, there are 2 major theories and it is believed that the Japanese cake has its roots in either the Spanish baked confection “Bizcocho” or the Portuguese baked confection “pão de ló”.

The original form was transmitted from Portugal to Japan and the first Castella cake was made around 1600. By the way, it is generally said that the origin of the word “Castella (カステラ)” derives from the Portuguese pronunciation for the Kingdom of Castile “Castella”.
