Nagasaki Castella : I Enjoyed the Japanese Sponge Cakes

“Castella (カステラ)” is a traditional Japanese “Wagashi (和菓子)” sponge cake made with hen’s eggs, wheat flour, sugar, and starch syrup.

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

The original cake of Castella was introduced from Portugal to Japan and the first Castella spongecake 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 of the Kingdom of Castile “Castella”.
