My Go-To Lemon Meringue Pie

My Go-To lemon meringue pie is a flour-thickened version that runs softer and more custardy than the cornstarch-based pies that dominate most cookbooks. Flour gives a less translucent, more cake-like filling that some bakers swear tastes more old-fashioned and homey.

The technique skips the cornstarch slurry step. Yolks, lemon juice, and zest go into the saucepan first, then flour, sugar, and butter. Boiling water joins last, cooking and thickening as everything stirs together over low heat. The result is a smooth, glossy curd with bright citrus notes and a softer mouthfeel.

A 2-egg-white meringue with just 3 tablespoons of sugar tops the pie. The meringue bakes at a high 450°F (230°C), which gives quick golden peaks but requires close watching so they don’t scorch.

Pro Tips

• Use a heavy-bottomed saucepan for even heat distribution. Thin pans create hot spots that scorch the bottom of the curd before the rest cooks through.
• Beat the yolks with the lemon juice and zest before turning on heat. The acid coats the eggs and prevents curdling when the heat hits.
• Add boiling water in a steady stream while stirring. Pouring it in too fast cools the pan and stalls the cook.
• Stir continuously across the bottom and into the corners with a flat-edged spatula. Flour settles fast and burns onto the pan if neglected.
• Watch the meringue closely at 450°F (230°C). At that high heat, the peaks go from pale to scorched in 60 seconds.

Variations

• Use Meyer lemons for a softer, more floral profile.
• Add 1 teaspoon of butter to the curd at the end for extra richness.
• Stir ½ teaspoon of cream of tartar into the egg whites before whipping for more stable peaks that resist weeping.
