Heading down cookie memory lane, here. I used to just love thumbprint cookies, and the various butter cookies that follow a similar recipe. They remind me of Christmas, holidays in general, and those old Hickory Farms catalogs that used to arrive around Halloween. I always wanted *something* from that catalog because the cookies and candies just looked so pretty!
As a note to the recipe, I think I would just use all butter rather than part shortening.
1/2 cup shortening (part butter)
1/4 c brown sugar
1 egg – separated
1/2 tsp vanilla
1 cup flour
1/4 tsp salt
3/4 c chopped nuts
Mix: sugar, shortening – egg [yolk] and vanilla. Blend in dry ingredients. Beat egg white slightly. Roll cookies into a ball, dip in egg white, then nuts. Place on ungreased cookie sheet. Press center. Cool, put jelly or frosting in center. 350 10-12 min.
