I found my old recipe.....probably should be updated for modern times (raw egg whites, no ice cream maker) but it has good bones Pina Colada Frozen Yogurt This recipe contains uncooked egg whites. the mixture could be processed in an ice cream maker without the egg white addition but will be harder. Ingredients 1 envelope gelatin 1/4 cup water 1 can (8 1/2 oz) crushed pineapple with juice 1 can (8 3/4 oz) cream of coconut 1 lg container (16 oz) plain yogurt 2 Tbs. rum 2 egg whites 3 Tbs. sugar Instructions Heat water in microwave for 1 1/2 minutes on high; sprinkle gelatin over, stir to dissolve. Blend pineapple, coconut cream, yogurt and rum in blender until smooth. Add gelatin to blender mixture, blend briefly. Pour into 9X9 pan. Freeze until partially frozen, stirring occasionally. (2-3 hours) Beat egg whites until soft peaks form, incorporate sugar. Spoon partially frozen yogurt mixture into a bowl; beat until smooth. Fold in egg whites. Freeze again until softly frozen (1-2 hours).
