Nagasaki Castella: A Classic Japanese Sponge Cake

“Castella (カステラ)” is a traditional Japanese sponge cake or wagashi made with hen’s egg, wheat flour, sugar, and starch syrup

whose name derives from the Portuguese pronunciation for the Kingdom of Castile, “Castella”.

As for the origin, there are two major theories, and it is believed that the 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, and Japan’s first Castella cake was made around 1600.
