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 ↓
Boiled Salmon
Ingredients
Directions
Cook the salmon

Butter and flour 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
- Butter
- Enriches the roux and adds richness and flavor to the sauce.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats.
- Peas
- Add color, sweetness and texture to the sauce.
The step that matters
Gradually add the milk to the roux. Adding the milk slowly while stirring lets the starch in the flour disperse evenly. Adding it all at once can create lumps, while stirring until the sauce heats and thickens lets the starch gelatinize into a smooth sauce.
Swap the peas
How well each one fits the dish's main ingredients (salmon, milk, butter, flour, pepper):
- Almondfits better
- Sesamefits about as well
- Walnutfits about as well
- Peasthe original
Fit is the average pairing score against salmon, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
“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.
