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 ↓
Chocolate Souffle
Ingredients
Directions
Make the base
Melt the butter in a small saucepan.
Stir in the flour and cook for 1 minute without browning.
Slowly add the milk, stirring until smooth and slightly thickened.
Remove from heat and mix into the beaten yolks and sugar until well combined.
Add the melted chocolate and stir for a few minutes, then let cool.
Rub a little butter over the top to prevent a crust from forming.
When ready to serve, stir the mixture to smooth it out.
Assemble and steam
Gently fold in the whipped egg whites until combined.
Pour the mixture into a buttered tin, filling it two-thirds full.
Line the tin with a strip of greased paper that rises above the sides.
Place the tin in a deep saucepan with enough hot water to cover half of it.
Cover the saucepan and simmer for 30 minutes, keeping it covered.
Serve
Serve immediately on a very hot dish, covering the top with a hot tin if needed.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Whipped whites trap air, lifting the soufflé as it cooks; yolks add richness and set the base.
- Flour
- Cooked with butter and milk, it thickens the base so it can hold the rising foam.
- Chocolate
- Provides the main flavour and some richness to the base.
- Milk
- Forms the liquid of the thickened base, giving it moisture and a smooth texture.
- Butter
- Adds richness and flavour, and greasing helps the soufflé release and rise cleanly.
The step that matters
Folding in the egg whites. Whites hold air only while they are whipped, so folding gently keeps that air in. Stirring or deflating the mixture makes the soufflé rise poorly and turn dense.
“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.
