1/2 C. Skim Milk
1/2 C. Nonfat Dry Milk Powder
1/8 tsp Cream of Tartar
4 tsp. Lemon Juice
2 tsp. Sugar
1/2 tsp. Vanilla

Place skim milk in small metal bowl, set in the freezer and let stand until ice crystals begin to form, about 15 minutes. Remove from freezer and add dry milk powder and cream of tartar. With electric mixer, beat at high speed until foamy. Beat in 1 tsp. lemon juice and continue beating until mixture begins to thicken. Beat in another tsp. of lemon juice, the sugar and continue beating until the mixture forms soft peaks. Add remaining lemon juice and continue whipping until stiff peaks form. Fold in vanilla and serve immediately as a desert topping. Mixture will deflate quickly.
