1 can evaporated milk, chilled
2 egg whites, beaten
1 (4 ounce) jar maraschino cherries
Blend milk and cherries and their liquid in a blender, only for a moment or two; cherries should not be too well blended.
Thoroughly whip egg whites. Fold in cherry mixture.
Freeze to desired consistency.
If you like a stronger flavor, add from 1/2 to 1 teaspoon almond extract.
