Cream butter or margarine, and add sugar; cream until light and fluffy. Mix in egg yolks. Combine flour and spices, and add to creamed mixture. Blend in cream. Stir in nuts, raisins, and dates. Pour filling into unbaked pie shell.
Bake at 350 degrees F (175 degrees C) for 35 to 40 minutes, or until set. Cool.
Based on the previous review, I baked this longer than the recipe suggested. May follow recipe exactly next time, and based on how great this tastes there WILL be another pie!
