Allow egg whites to stand at room temperature for 30 minutes. In a large mixing bowl combine egg whites, vanilla, and cream of tartar. Beat with an electric mixer on medium speed about 1 minute or until soft peaks form (tips curl; see photo 1, page xxx).
Gradually add sugar, 1 tablespoon at a time, beating on high speed about 5 minutes or until mixture forms stiff, glossy peaks (tips stand straight; see photo 2, page xxx) and sugar dissolves (rub a small amount between two fingers; it should feel completely smooth).
Immediately spread meringue over hot pie filling, carefully sealing to edge of pastry (see photo 2, page xxx) to prevent shrinkage. Bake as directed in recipes.
