Grandma Rose made this recipe for Lemon Meringue Pie for many years. This recipe has definitely stood the test of time.
Make crust according to package directions for one-crust pie. Spoon filling into baked pie shell. Make meringue.
Beat egg whites with salt and cream of tartar until foamy. Continue beating until soft peaks form. Sprinkle 1 tablespoon of sugar at a time over egg whites, beating well after each addition, beat whites until stiff peaks form.
Bake in a 350 degree oven until whites are golden brown, about 10 to 15 minutes. Watching closely.
