Our recipe tester's grandmother Josephine Rege has been making her version of lemon angel pie for more than 60 years. We updated her recipe, and the result became an instant Martha (and test-kitchen) favorite.
This recipe is one of our Better Basics: 10 New Takes on Family Favorites, see the others.
Room-temperature egg whites will produce the most voluminous meringue. For just the right texture, whip the whites until they hold stiff, glossy peaks--but keep the mixture still spreadable enough that you can make decorative swirls in it as you top the pie.
This recipe comes courtesy of Diane Rasberry of Baton Rouge, Louisiana. She says the chocolate filling of this pie is balanced out by the not-too-sweet meringue topping. Pick up a crust at the store, or bake Our Favorite Pie Crust. Spread the meringue to the crust's edge so that it seals and doesn't shrink.
