Ostkaka, "ost" meaning "cheese" and "kaka" meaning "cake" in Swedish (the definition of "kaka" includes "cookie" but is a wider concept), also known as Swedish cheesecake or Swedish curd cake, is a Swedish dessert that has its roots in two different parts of Sweden, Hälsingland and Småland, though there are some differences between ostkaka from Hälsingland and ostkaka from Småland.
The dish has a rather firm consistency and subtle, creamy taste with a hint of almonds. It is usually eaten lukewarm with different jams, typically cloudberry, cherries or strawberry though lingonberry is often used, as well as fruits, whipped cream or, more rarely, ice cream. The reason for eating ostkaka while it is lukewarm is that if eaten too warm, the delicate flavors of the ostkaka will not come through, and if eaten too cold the consistency will be too firm and heavy.
Despite the similarity in literal translation, ostkaka should not be confused with cheesecake which is a layered cake. Swedes typically call the latter by its English name, sometimes making it "American Cheesecake", to avoid confusion. Though even then, Scandinavian restaurant menus sometimes confuse the two.
