How-to Top a Pie with Meringue
Meringue should be spread over hot, not cool, filling. The hot filling helps set the bottom of the meringue and minimizes weeping (a watery layer between the meringue and the filling). Spread meringue over filling and seal to the edges of pie crust. Bake according to recipe directions. Cool pie on a wire rack in a draft-free area for 1 hour. Chill for 3 hours before cutting. Store in the refrigerator.
