Lemon meringue pie is a classic dessert that combines a tangy lemon filling with a fluffy meringue topping. The filling is made with fresh lemon juice, zest, sugar, eggs, and cornstarch, creating a smooth and tart custard-like texture. The meringue is made by whipping egg whites and sugar until stiff peaks form, then baked until golden brown. The combination of the sweet meringue and tart lemon filling creates a perfect balance of flavors. This pie is a refreshing and delicious treat that is sure to impress.
