What Swedish region holds the world championship in ostkaka?

The world championship in ostkaka is held in Hälsingland, Sweden.

Ostkaka is a traditional Swedish curd cake whose name literally means “cheese cake.” It has two major regional traditions: Hälsingland in central Sweden and Småland farther south. Hälsinge ostkaka is relatively smooth, firm and sliceable, while the Småland style is softer and more grainy.

Traditional ostkaka is made by curdling warm milk with rennet, then baking the resulting curd. It is commonly served lukewarm with fruit sauce, jam, berries, cream or vanilla ice cream. Despite its English nickname, it is not the same dessert as American cheesecake.

Hälsingland’s championship association reflects the region’s strong ostkaka tradition. Småland is therefore a tempting wrong answer: it is equally important to the cake’s history, but the world championship is specifically held in Hälsingland.
