Although eaten refrigerated, not frozen, this rich dessert melts in your mouth like ice cream! One of it's special assets is being able to make it ahead and freeze to have on hand for special occasions. Mother made this often, and it is still my favorite dessert. Cooking time includes chilling time. Variation: For Gluten-intolerant people: Omit pie crust and spoon filling into individual parfait glasses and garnish with whipped cream and chocolate shavings!
