Stand the fruit on a flat end. Using a sharp knife to follow the curves of the sides, cut off the peel down to the flesh. Holding the fruit over a bowl, cut the segments free of the membrane on each side. When ready to serve, place shell bottoms on dessert plates. Pat grapefruit segments dry with paper towel. Place one in bottom of each pastry shell. Spoon in a rounded 1/4 cup of the cream cheese filling. Place top of pastry shell over mixture. Top with another grapefruit segment. Spoon sauce over the top. Makes 6 servings. 2015 Ocean Spray® "Surprisingly Versatile" Grapefruit Recipe Contest Third Place Winner Ronna Farley
