Make a 9 inch gluten free pie crust, and pre-bake it at 350 degrees for 20 minutes or until it is as brown as you like it. Set the pie shell aside to cool.
1 cup sugar
1/4 cup gluten free gravy flour (see below)
3 Tablespoons cornstarch
1/4 teaspoon salt
2 cups water
4 egg yolks, beaten
1 tablespoon butter or gluten free vegan margarine
1/4 cup fresh squeezed key lime juice (requires 8-10 tiny key limes or 4 regular limes)
1 teaspoon finely grated lime zest
4 egg whites
1/4 teaspoon cream of tartar (to stabilize the meringue)
6 teaspoons sugar
1 teaspoon vanilla
Combine the sugar, gluten free gravy flour, cornstarch and salt in a 2-quart saucepan. Gradually stir in the 2 cups of water. Cook at medium heat, stirring constantly with a whisk, until thickened. At this point, it will taste bland. Don’t taste it now.
Stir a small amount of the hot mixture in to the egg yolks, then a little more, then a little more, until half the hot mixture has been added to the yolks. Combine the yolk mixture with the rest of the mixture in the saucepan, whisking constantly and cooking for two minutes. Whisk in the butter or margarine. The aim of this process is to mix everything without getting lumps of hard-boiled egg yolk. Stir in the key lime juice and zest. Cool slightly, then pour in to the cooked pie shell.
Preheat the oven to 350 degrees. Beat the egg whites and cream of tartar for the meringue using a hand beater or an electric beater until the whites form soft peaks that hold their shape. Gradually beat in the sugar and the vanilla until the meringue is glossy and holds well. Spread the meringue carefully all over the pie to cover the pie completely. Bake the pie for 6 minutes, or slightly longer, to brown the top of the meringue. Cool the pie completely before serving.
