The Japanese term カステラ (kasutera) and the Korean term 카스테라 (kastera) are etymologically derived from the Portuguese "Pão de Castela". But does "kasutera" and "kastera" refer to the same foodstuff, or a different foodstuff?


I’ve come to the conclusion that Koreans use “kastera” to describe almost every type of baked product that’s Western in origin.

Castella = Kastera = Kasutera says:

These baked products are a cheap, guilty indulgence -- they are good -- but I don't consider them "genuine" Japanese kasutera, which I have come to understand is not as spongy and comes in a rectangular shape.

Are they the same foodstuff, or are they different foodstuffs? Would it be more logical to say "I prefer kastera over kasutera", or would "I prefer the way Koreans do kastera over the way Japanese people do it"?

1 Answer 1


There is a particular baked good called kastera in Korea, but they pretty much use the term as a generic name for any Western-style sweet cakes (source: my Korean mother-in-law). So the answer is yes and no. You will find a kastera equivalent to Japanese kasutera, but it is a subset of the kastera set.

The closest comparison I can think of would be the term "barbecue." It would very specifically mean slow-smoked meat in certain regions of the United States. In other regions, "barbecue" is a bigger tent, and includes, among other things, anything that is cooked on a grill.

  • Koreans like to use it as a generic name for a sponge cake with no fillings/toppings, perhaps. Castella is one of my favorite treats at Korean bakeries, and while they might have additional flavors (green tea, coffee, etc.) or different shapes or airier/denser cake... it's ultimately just like "barbecue" like you mention. I haven't seen that label being used for any other Western-style sweet cakes. Commented Sep 18, 2014 at 19:43
  • I'm just going by what the M-I-L said. I know better than to argue. :)
