Leftovers with leftovers.
Combine 2 cups of cooked rice and about 1 cup of milk. Heat in high-power microwave for 5 minutes: the rice will be softened and the milk will have come to a boil. Put it in the refrigerator until it’s cooled. (I was impatient and I transferred the mixture to a metal mixing bowl and chilled it in an ice-water bath; it took 5 minutes.) Combine 1 cup of Mascarpone Cream, the cooled milk-rice mixture and 1/2 teaspoon of vanilla. Return to refrigerator to chill before serving.
It’s not low in calories, but it sure tastes good.
