My Lemon Custard

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

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

  2. Separate the eggs.

Make the custard

  1. In a bowl, mix the yolks, sugar, butter, and corn starch.

  2. Add the juice and grated rind of the lemon to the mixture.

  3. Beat the egg whites until stiff and fold them into the custard mixture.

Bake

  1. Pour the custard into a pie crust and bake until set.

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

What each ingredient does

Eggs
Yolks thicken the custard and whites, beaten stiff, lighten its texture.
Sugar
Adds sweetness and balances the sharp lemon juice.
Butter
Adds fat for a rich, tender texture and smooth mouthfeel.
Corn starch
Thickens the custard so it sets firm when baked.
Lemon
Provides acidity and aroma from its juice and rind.

The step that matters

Folding in the egg whites. Beaten whites hold air that gives lightness; overmixing or deflating them during folding loses that volume, leaving a denser custard.

Swap the lemon

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

  1. Vanillafits better
  2. Coconutfits better
  3. Figfits about as well
  4. Lemonthe original

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