Castella is a light, moist Japanese sponge cake known for its fine texture, subtle sweetness, and distinctive rectangular shape topped with a glossy caramelized crust.
Castella originated in 16th-century Japan, introduced by Portuguese missionaries and traders during the Nanban trade period. Its name derives from the Portuguese term "Pão de Castela," meaning "bread from Castile," reflecting its Iberian roots. Over time, Castella was adapted to Japanese tastes and became a celebrated specialty of Nagasaki, symbolizing the region’s historical openness to foreign influences.
Castella belongs to the sponge cake family, characterized by a batter leavened primarily through air incorporation rather than chemical agents or fats. Unlike butter cakes, Castella contains no added fat, relying on whipped eggs and starch syrup to achieve its moist, tender crumb.
Traditionally baked in long rectangular loaf molds, Castella presents a single-layer, loaf-like form with a fine, even crumb. Its surface is marked by a glossy, caramelized top that contrasts with the pale golden interior, offering an inviting visual balance.
Castella is commonly sliced into rectangular pieces and enjoyed as a snack or dessert. It pairs especially well with green tea and is frequently served during tea ceremonies, family gatherings, and as a thoughtful gift or souvenir, particularly in Nagasaki where it holds cultural prominence.
