1/2 c. sweet butter
1/2 c. sweet butter, melted and cooled
3 egg yolks
2 1/2 c. flour
1/4 c. sugar
1 tsp. vanilla

Cream both solid and melted butter together with sugar and yolks. Add vanilla. Work in flour well, until dough is smooth. Cut in small even pieces - the size of a walnut - roll in your hand into a ball and wit the tip of little finger make a rather deep impression in the middle. Place on a greased baking sheet, brush with beaten egg and sprinkle with chopped almonds (optional). Bake at 400 degrees until rosy. When cool, sprinkle with sugar and fill the dent in the middle with any tart red jam.
