Beat egg yolks (save the whites for later). Add ½ c. sugar, pumpkin, milk, ¼ tsp. salt, cinnamon and nutmeg. (For added flavor, grind your own cinnamon and nutmeg.) Cook in a heavy saucepan over low heat, stirring constantly, until thickened. Mix in gelatin until completely dissolved. Chill about 2 hours in refrigerator.
