Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
A Plain Sweet Souffle
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Mix flour or ground rice with ½ cup of milk to form a smooth batter.
Gradually add 1 cup of milk while stirring over medium heat for 10 minutes.
Stir in sugar and lemon rind, then mix for 3 minutes.
Pour the mixture into a bowl and beat in the egg yolks gradually.
Bake and serve
Whisk the egg whites until stiff peaks form.
Butter a baking pan and gently fold in the egg whites.
Pour the souffle mixture into the pan and bake at 350°F (175°C) for 30 minutes.
Serve immediately after removing from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour or ground rice
- Thickens the milk into a stable base that holds the soufflé's structure.
- Egg yolks
- Add richness and set during baking to give the soufflé body.
- Egg whites
- Whipped into foam, they trap air that lifts the soufflé as it bakes.
- Milk
- Provides moisture and liquid that the starch thickens into the base.
The step that matters
Folding in the egg whites. Folding gently keeps the air in the whipped whites. Overmixing deflates the foam, so the soufflé rises less and turns dense.
Swap the lemon
How well each one fits the dish's main ingredients (flour, milk, sugar, egg, butter):

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