1 cup butter, 1 cup sugar, 1 egg yolk, 1 1/2 cups coarsely chopped filberts, almonds, or pecans, 1/2 cup poppy seeds, 1/2 t. cinnamon, 1/2 t. ginger, 1 t. vanilla extract, 2 - 2 1/2 cups flour.
Cream softened butter & sugar, add egg yolk then rest of ingredients. Add enough flour to make firm but not sticky dough. DO NOT knead or work dough. Form into 2 rolls 1 1/2" in diameter. Wrap in waxed paper and chill at least 4 hours or overnight to make firm.
Slice with serrated knife into 1/4" slices. Lightly grease a cookie sheet. Bake in a preheated 325 degree oven for about 12 minutes or until lightly tanned.
Makes 48 cookie slices. Dough can be frozen before baking to use at a later date.
