Cream shortening and sugar. Add eggs, orange juice, rinds, vanilla and sour milk. Mix well. Add all dry ingredients which have been sifted (NOT! I'm lazy) together. Blend everything together well. Optional one cup of nuts. Drop by teaspoon on greased cookie sheet, (I used teflon cookie sheet ~ no greasing) Bake at 350% for 5 to 8 minutes. ICING: Beat it all together and slap on the VERY COOLED DOWN cookies. This makes a cake like cookie just exploding with orange flavor
