These cookies are a family tradition at X-mas time.
I suggest doubling or trippeling this recipe as it really doesn' t make much.
A double batch makes about 36, 1 1/2 inch cookies.
1/2 c. shortening/butter
1/4 c. brown sugar
1 egg yolk
1/2 tsp vanilla
1 c. flour
1/4 tsp salt
On the side, have the egg white and around 3/4 chopped nuts (I recommend walnuts)
Roll into 1 inch balls. Dip in egg white. Roll in finely chopped nuts. Place about 1 inch apart on ungreased cookie sheet. Bake 5 min at 375 degrees. Remove from oven and quickly press thumb on top of each cookie to make a depression. Return to oven and bake 8 minutes longer. Cool.
Fill the depression with candied fruit, jelly, or tinted frosting. We always do the last one (powdered sugar, almond extract and a bit of cream until smooth but thick - add whatever color you want).
