In a large bowl, whisk flour, baking powder, and salt.In a medium bowl, grate butter.Crumble the dry cottage cheese into with the butter and mix them together.
Mix the butter and cheese with the flour blend.Using your hand, mix into a dough and knead for about 5 minutes.
Roll out the dough on a floured wooden surface, and fold it. Cover and refrigerate for 30 minutes.Repeat kneading, rolling, and resting in refrigerator twice.When ready, roll the dough to a 1-inch thickness, and cut into rounds with a biscuit cutter.Preheat oven to 375F.With the point of a sharp knife, score the tops of the biscuits in a lattice.Beat the egg yolks with 1 tsp of water, and brush the glaze onto the biscuit tops.
Sprinkle cheese on top.
Bake for 25 min, or until golden brown.Cool on a wire rack and serve as a snack, with soup, or, as George suggests, as an accompaniment with wine. Mmm. Now there's an idea!
