Quark, a mild fresh cheese, yields a particularly moist biscuit.
Preheat oven to 450 degrees F.
Sift flour, sugar, baking powder and salt into a large bowl. Whisk quark and water in a small bowl. Make a well in the dry ingredients. Add quark mixture and stir with a fork just until blended. (Do not overmix.)
Turn the dough out onto a lightly floured surface. Knead a few times and pat into a 1-inch-thick circle. Cut out biscuits with a floured 2-1/2-inch round cutter and place on an ungreased baking sheet. Press dough scraps together and repeat to make 12 biscuits in all. Bake until tops are golden and firm to the touch, 12 to 15 minutes. Serve warm.
Quark is a mild, creamy fresh cheese that is low in fat. Pureed farmer's cheese can be substituted.
