3/4 lb butter, softened
1-1/4 C sugar
2 eggs
4 C flour

Preheat oven to 350 F. Blend the butter, sugar, and eggs in a large bowl. Add the flour and knead well with floured hands. Divide dough into two and press into pie plates. Prick the top of each one all over with a fork. Bake for 30 minutes, until it begins to brown. Allow to cool, turn out onto foil, and wrap. Wrap again in a towel and place in a tin with a tight-fitting lid. Allow to age for a month. To serve, break into pieces (do not cut).
