<human>:  How do I make a lemon meringue pie?
<bot>: To make a lemon meringue pie, start by preheating your oven to 375°F. Next, make your pie crust by combining 9-inches of store-bought or homemade pastry dough with 3 tablespoons of sugar. Once your dough is ready, press it into a 9-inch glass pie plate and bake it for 15 minutes. Now, add the filling: In a bowl, whisk together 2/3 cup of sugar, 1/4 cup all-purpose flour, 2 tablespoons finely grated lemon zest, 1/2 teaspoon of salt and 2/3 cup of freshly squeezed lemon juice. Slowly pour the mixture into the pre-baked crust, then cover it with a layer of sliced lemons and bake for 25 minutes. Finally, make the meringue topping: Beat together 4 large egg whites and 1/4 teaspoon of cream of tartar, then gradually add 1/2 cup of sugar and beat until the mixture is thick and glossy. Spread the meringue on the cooled lemon filling and bake for 10 to 15 minutes until the meringue is lightly golden. Allow the pie to cool before serving.
