Ingredients:

  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   2      cups          sugar
   4      tablespoons   cocoa powder
     1/2  cup           milk
     1/2  cup           shortening
   1      teaspoon      vanilla

Preparation:

Bring first 4 ingredients to full boil and boil for exactly one minute. (In very damp weather, boil for 1 1/4 minutes). Add vanilla and beat until spreading consistency. It helps to set the pan in ice water, while beating, but do not get ANY into the frosting.
