peanut butter blossoms

one of my favorite holiday cookies:

1 3/4 C sifted flour
1 tsp baking soda
1/2 tsp salt
1/2 C. shortening
1/2 C. peanut butter
1/2 C. sugar
1/2 C brown sugar
1 egg
2 Tbs. milk
1 tsp vanilla

cream together the shortening, peanut butter, sugar, and brown sugar. add the egg, milk, and vanilla. mix until incorporated. blend in the dry ingredients. shape into balls. roll the cookie dough balls in sugar. place on ungreased cookie sheet. bake at 375 degrees for 8 minutes. remove from the oven and place a chocolate kiss on top of each cookie, pressing down so the cookie cracks around the edge.
