Lemon Cream 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, egg yolks, and flour.

  3. Add enough milk to fill the pie plate and pour the mixture into an under crust.

Bake and top

  1. Bake until nearly done.

  2. Remove from the oven and top with a frosting made from beaten egg whites and powdered sugar.

  3. Return to the oven and brown slightly.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Egg yolks
Thicken the filling and add richness as they set with the flour.
Egg whites
Beaten into a frosting that bakes to a light, set topping.
Flour
Thickens the lemon filling so it holds its shape when cut.
White sugar
Sweetens the filling and balances the sharpness of the lemon.
Lemon juice
Adds the sharp, acidic flavor that defines the pie.

The step that matters

Return to the oven and brown slightly. Meringue-style toppings can over-brown quickly because sugar caramelizes at high heat. Watch closely so the topping turns golden without scorching, and the filling stays set underneath.

Swap the lemon

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

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