Sweet Potato Marshmallow Meringue Pie
In a large bowl combine 4 egg whites (from pasteurized eggs), 1 tsp. cream of tartar, and 1/8 tsp. salt. Beat with a mixer on medium to high until foamy. Add 1/4 cup granulated sugar, 1 Tablespoon at a time, beating until soft, glossy peaks form (tips curl). Add one 7-oz. jar marshmallow creme in large spoonfuls while beating on medium. Beat until smooth and just shy of stiff peaks (the tips won't quite stand straight).
If you can't find hazelnut meal, pulse 4 cups toasted hazelnuts in a food processor until finely ground.
Halve the crust recipe and press into an unlined 9-inch springform pan; parbake per recipe. Add filling and bake 50 to 60 minutes or until set.
