|FOR THE MERINGUE SHELL:
In a large mixing bowl beat egg whites, vanilla, and cream of tartar with an electric mixer on medium speed till soft peaks form (tips curl). Gradually add sugar, 1 tablespoon at a time, beating on high speed about 7 minutes, or till very stiff peaks form (tips stand straight) and sugar is almost dissolved. Using a spoon or spatula, spread meringue onto bottom and sides of a well-greased 10-inch pie plate, building the sides up to form a shell. Bake in a preheated 300° oven for 45 minutes. Turn off oven. Let dry in oven with door closed for 1 hour (do not open oven door). Cool on a rack.
|FOR THE FILLING:
In a medium saucepan stir together sugar and cornstarch. Stir in milk. Cook and stir over medium heat till thickened and bubbly. Reduce heat; cook and stir for 2 minutes more. Remove from heat. Gradually stir about half of the hot mixture into egg yolks. Return all to saucepan and bring to a gentle boil. Reduce heat. Cook and stir for 2 minutes more. Remove from heat. Stir in sour cream, lemon peel, and lemon juice. Pour filling into a bowl. Cover surface with plastic wrap. Cool without stirring. Spoon filling into meringue shell. Cover and chill for 2-24 hours.
|Just before serving, if desired, garnish with dollops of whipped cream, lemon peel, and raspberries.
