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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the base while beaten whites create the airy lift that makes the soufflé rise.
- Flour
- Starch thickens the butter and milk into a stable sauce that holds the soufflé structure.
- Butter
- Fat enriches the flour roux and adds flavour to the base.
- Milk
- Liquid combines with the flour to form the thick white sauce base.
- Haddock
- Minced cooked fish provides the main flavour and bulk of the soufflé.
The step that matters
Add the beaten whites. Whites must be beaten to hold air and folded gently into the base so the soufflé rises. Overmixing deflates the foam, while underbeaten whites fail to lift the mixture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
