Quark

[kwark, kvark] A soft, unripened, cow's milk cheese with the texture and flavor of sour cream, Quark comes in two versions-low-fat and nonfat. Though the calories are the same in low-fat Quark and low-fat sour cream (about 35 per ounce), the Quark's texture is richer. It has a milder flavor and richer texture than low-fat yogurt. Quark can be used to top baked potatoes, and as an ingredient in a variety of dishes including cheesecakes, dips, salads and sauces. In Austria, it's referred to as Topfen; in Central Europe it's spelled Quarg and Kvarg.
