Why it works: Butter and milk 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 ↓
Tomato Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Melt the butter in a saucepan.
Stir in the flour, then gradually add the milk.
Add the seasonings, grated cheese, and tomato pulp.
Mix in the egg yolks.
Fold and bake
Fold in the stiffly beaten egg whites.
Pour into a buttered baking dish and place it in a larger dish filled with hot water.
Bake at 400°F (200°C) for about 30 minutes.
Serve immediately.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by folding give the soufflé its light, risen structure; yolks enrich the base.
- Flour
- Thickens the melted butter and milk into a sauce that holds the soufflé together.
- Butter
- Fat that forms the roux with the flour and adds richness to the base.
- Milk
- Liquid that, with the flour and butter, forms the thick base for the soufflé.
- Tomato pulp
- Adds moisture and tomato flavour to the base.
The step that matters
Fold in the stiffly beaten egg whites. Folding gently keeps the air in the whites. Stirring or overmixing deflates the foam, so the soufflé rises less and turns dense.

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