Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
A Plain Souffle
Ingredients

Fold in the stiffly beaten egg whites.
Pour the mixture into a greased baking dish.
Steam gently for 1 hour.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam, they trap air and make the soufflé rise and turn light.
- Egg yolks
- Add richness and emulsify the base, and their proteins help set the structure as it cooks.
- Flour
- Thickens the butter and milk into a stable base that holds the air from the whites.
- Butter
- Fat that enriches the base and, with the flour, forms the roux that thickens the milk.
- Milk
- Liquid that hydrates the flour and, once thickened, forms the body of the base.
The step that matters
Fold in the stiffly beaten egg whites. Folding gently keeps the air in the whites. Stirring or deflating them makes the soufflé fall and turn dense instead of rising light.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, flour, sugar, milk, egg):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, flour, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
