Make a rich biscuit dough; roll out and place on a well-buttered pie-dish. Then mix ½ pound of cottage cheese with a pinch of salt, ¼ cup of melted butter, ½ cup of sugar, ½ lemon grated, 2 yolks of eggs and ½ cup of currants; add the whites beaten stiff. Fill the pie with the cheese. Serve hot or cold with coffee.
