Apricot Meringue Pie

The egg yolk acts as both a thickener and emulsifier, binding the fruit filling while adding richness. Baking the filling first allows it to set properly before adding the meringue, preventing a soggy topping. The brief resting period after initial baking releases steam and stabilizes the filling temperature, which prevents the meringue from weeping. Adding sugar to egg whites creates a more stable foam by interfering with protein bonding, while the slow oven gently denatures the proteins to create a crisp, golden exterior without overcooking.
