Kolache is a Czech or Slovack pastry filled with either fruit (such as apricots, prunes or raspberries) or meats and/or cheeses.
Beat smooth, then add butter mixture and enough flour to make a medium soft dough. (as stiff as can be mixed with a spoon). Knead with a wooden spoon. Let dough rise in a warm place until doubled.
Turn dough out on board and knead down. Let rise again for a few minutes. It will be easier to handle. Then make into rolls.
Shape, pinch or cut off with a spoon, a piece of dough the size of a large walnut, smooth it round and lay rolls two inches apart on buttered cookie sheet. Let rise until doubled, then with finger tips, stretch, do not mash, roll into the shape of a tiny pie shell. Fill with thick jam or prune filling. Brush dough edges with butter and let rise again until dough is light (about 15 minutes).
Bake about 20 minutes at 375 degrees.
