Dip some scissors in hot water. Cut candy up into small pieces. Let them fall on floured wax paper. Toss with small amount of flour when finished cuttin, so they don't stick together. Cream together the sugars and margarine. Mix in the eggs, milk and vanilla. Sift together the flour, baking powder, soda and salt. Add to the creamed mixture. Add the coconut and orange slices. Cool dough in freezer until it's very stiff. Roll with hands into balls the size of walnuts. Place on ungreased cookie sheet 2" apart and bake at 350 for 15-20 minutes. Makes about 5 dozen.
