Lemon Souffle

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the base

  1. Preheat the oven to 400°F (200°C).

  2. Beat the yolks of the eggs until light colored and thick.

  3. Gradually add the powdered sugar, then mix in the grated lemon rind and lemon juice.

Make the soufflé

  1. In a separate bowl, beat the egg whites with the salt until stiff.

  2. Gently cut and fold the yolk mixture into the egg whites.

  3. Pour the mixture into a buttered baking dish.

  4. Bake until well puffed and lightly browned.

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

What each ingredient does

Eggs
Whipped whites trap air and provide the structure that lifts the soufflé, while yolks add richness.
Powdered sugar
Sweetens the base and dissolves easily into the beaten yolks, adding body to the batter.
Lemon juice
Adds acidity that brightens the flavor and balances the sweetness.
Grated lemon rind
Contributes aromatic oils that give the soufflé its lemon fragrance.

The step that matters

Folding the yolk mixture into the whites. Folding gently keeps the air bubbles in the whipped whites intact. Stirring or deflating them makes the soufflé heavy and limits how much it can rise in the oven.

Swap the lemon

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

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