カステラ/Castella is a baked cake.
It is often found at patisseries in a rectangular shape with a soft, pale inside and browned top and bottom.
It can also be found at festivals in ball form in a variety of flavours.
This is a shop display of bagged castella balls.
These balls are a nostalgic sweet treat from the childhood of most Japanese people.
The recipes originate from Spain (castila) but was introduced by the Portugese.
It’s a souvenier food from Nagasaki (where Portugese traders introduced the cake) and sold in almost 30cm long boxes!
You can also find Japanese flavours – like the above sweet potato, or the matcha green tea below:
