Cook together the sugar, spice, pumpkin, cornstarch and Carnation milk until the mixture forms a soft ball in cold water or reaches 235°. Do not stir while cooking. Add vanilla; stir lightly and cool in ice water to 110°. Beat until creamy and fudge loses its gloss. Pour onto a buttered plate or waxed paper and cut into small squares when nearly cool. Can be "worked" in hands (instead of beating) and shaped into rolls for slicing. Work in a few nuts, if desired. 1/2 again of this recipe will use one small can of Carnation.
