Ostkaka, also called Swedish cheesecake, is from Sweden.
The name combines the Swedish words ost, meaning “cheese,” and kaka, meaning “cake.” Unlike dense American cheesecake, ostkaka is a crustless Swedish curd cake traditionally made by curdling milk with rennet, then baking the resulting curds with ingredients such as cream, eggs, sugar, and almonds.
The dish has two especially well-known regional traditions: a smoother, firmer style from Hälsingland and a softer, grainier style from Småland. It is commonly served lukewarm or cold with whipped cream, fruit sauce, jam, or berries. The English label “Swedish cheesecake” can cause confusion because ostkaka is related to cheesecake by its dairy base, but its texture and preparation are quite different. Sweden has celebrated an Ostkaka Day on November 14 since 2004.
