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 ↓
Vanilla Soufle
Ingredients
Directions
Prepare
Butter a 1½ pint soufflé tin and tie a band of paper around it, extending 2 inches above the top.
Melt 1 oz of butter, then add the flour and mix well.
Stir in the milk and sugar, cooking over low heat until thickened.
Make the soufflé
Remove from heat and add the yolks of 3 eggs one at a time, beating well after each addition.
Beat the 4 egg whites to stiff peaks and gently fold into the mixture.
Add the salt and vanilla essence, then pour into the prepared tin.
Steam for 25 minutes.
Serve
Turn out onto a hot dish and serve immediately with custard poured around.

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
- Eggs
- Egg whites whipped to stiff peaks give the soufflé its light, airy structure, and yolks add richness.
- Flour
- Cooked with butter and milk, flour thickens the base so it can hold the whipped egg whites.
- Milk
- Milk forms the liquid base of the thickened sauce that the eggs are folded into.
- Butter
- Butter, cooked with flour, forms the roux that gives the base its body and richness.
- Castor sugar
- Sugar sweetens the base and adds a little body to the thickened mixture.
The step that matters
Folding in the egg whites. Whites beaten to stiff peaks trap air that makes the soufflé rise. Folding gently keeps that air in; stirring or deflating the mixture leaves a dense result.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, milk, butter, sugar, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against egg, milk, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
