Beat egg whites and cream of tartar until foamy.
Gradually add sugar and beat until stiff, glossy peaks form.
Beat in vanilla.
Spread meringue over the warm filling, making sure it touches the crust edges (prevents shrinking).
4. Bake
Bake at 350°F (175°C) for 15 minutes, or until meringue is lightly golden.
Cool 1 hour, then refrigerate 3–4 hours before slicing.
Tips for a perfect pie
Spread meringue on hot filling so it doesn’t separate.
