Mother's Lemon Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the filling

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the lemon juice, lemon rind, sugar, butter, milk, and eggs until well combined. If the mixture does not fill the pie plate, add more milk.

Make the meringue and bake

  1. For the meringue, beat the egg whites with powdered sugar until stiff peaks form.

  2. Spread the meringue over the baked pie smoothly.

  3. Return the pie to the oven and bake until the meringue is lightly browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set the lemon filling into a thick custard as they cook.
Egg whites
Whipped into stiff peaks to form the airy, stable meringue topping.
White sugar
Sweetens the lemon filling and helps thicken it with the eggs.
Lemon juice
Provides the sharp acidity that balances the sweetness of the filling.
Butter
Adds richness and a smooth, tender texture to the filling.

The step that matters

Beat the egg whites until stiff peaks form. Egg whites must be whipped to stiff peaks to trap air and hold their shape. Under-beaten whites weep or collapse in the oven, while any trace of fat or yolk prevents them from whipping fully.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, butter, milk, egg):

Fit is the average pairing score against sugar, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
