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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod fish
- Provides the main body and flavour of the dish.
- Heavy cream
- Adds richness and a smooth, silky texture.
- Milk
- Forms the liquid base of the cream and adds mild sweetness.
- Flour
- Thickens the liquid as it heats, giving the cream body.
- Eggs
- Enrich and slightly set the cream when stirred in off the heat.
- Butter
- Adds fat for flavour and a smooth mouthfeel.
The step that matters
Stir in the eggs off the heat. Eggs scramble if they meet a boiling liquid. Removing the pan from heat first lets them blend in and gently thicken the cream without curdling.
Swap the walnut
How well each one fits the dish's main ingredients (fish, milk, cream, butter, pepper, flour, egg):
- Almondfits about as well
- Walnutthe original
- Pistachiofits less well
- Beansfits less well
Fit is the average pairing score against fish, milk, cream, butter, pepper, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
