Favorite Lemon Pie

This favorite lemon pie is a fascinating bit of American Depression-era cookery that uses water-soaked bread as the thickener instead of cornstarch or flour. Before pantry staples were always available, bread was the common stretcher and binder in cookies, sauces, and yes, custard pies.

The technique might sound strange today, but it produces a remarkably smooth, slightly textured custard that’s distinct from any modern lemon pie filling.

The bread soaking step is the make-or-break detail. Six slices of crustless white bread get briefly dipped in water, then squeezed firmly to remove most of the moisture before being torn into the double boiler.

This creates a paste-like texture that disappears into the cooking lemon custard while still providing the structural body needed to hold a slice.

A double boiler (gentle indirect heat) is essential here. Cooking the egg yolk and lemon juice mixture over direct heat would scramble the eggs, but the steam-warmed top pan brings everything up gradually until the mixture thickens evenly.

The traditional meringue topping (egg whites whipped with sugar to soft-firm peaks) bakes into a golden cap that adds visual drama and balances the tart filling beautifully.

Pro Tips

• Use plain white sandwich bread, not artisan or whole grain. Other breads have too much flavor and texture.
• Squeeze the soaked bread firmly. Wet bread makes a watery, weeping custard.
• Whip the egg whites in a spotlessly clean, dry bowl. Any trace of fat or yolk prevents proper whipping.
• Spread the meringue all the way to the crust to seal in the filling and prevent shrinking during baking.

Variations

• Add the zest of one lemon to the custard for a more intense citrus flavor.
• Swap lemon juice for fresh lime or grapefruit juice for a different citrus profile.
• Top with whipped cream and toasted coconut flakes for a tropical twist.
