This one is a delight for sure, retro jell-o, err gelatin always is a delight. Apples are the perfect thrifty fall food and we are making good use of them this month! Note the reduced sugar version! Good thing since you serve it with custard sauce!

Apple Delight

1 tablespoon gelatin
¼ cup cold water
1 cup sugar
½ cup water
¹/₈ teaspoon salt
1 lb tart cooking apples
3 tablespoons lemon juice
¼ teaspoon grated lemon rind

Soak gelatin in cold water. Boil sugar and the ½ cup water for 3 minutes. Add salt and pared, sliced apples (should be 2 cups); cover, simmer until tender. Remove from heat, stir in gelatin. Add lemon juice and rind; cool. Pour into mold or bowl; chill until firm. Unmold and serve with cold Custard Sauce or cream. 4 servings.
Variation: To save sugar, substitute 1 cup sweet cider for the ½ cup water, reduce sugar to ½ cup and omit lemon juice and rind. The Modern Family Cookbook
