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 ↓
Salmon Soup
Ingredients
Directions
Prepare the salmon
Take 1 pound fresh or canned salmon, cover with boiling water and simmer 15 minutes.
Take out skin and bones and mash through a colander.
Make the soup
Bring 1 pint each of milk and veal stock to the boil.
Stir in 2 tablespoons flour rubbed with 1 tablespoon butter.
When it thickens, put in the salmon.
Take up when it reaches the boil again.
Season with salt and pepper.
If no stock, use that much more milk and boil in it a little onion, bay leaf, and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon (in the method)
- Provides the main protein and the characteristic flavor of the soup.
- Milk
- Forms the liquid base and adds richness and creaminess.
- Flour
- Thickens the liquid as its starch swells with heat, giving the soup body.
- Butter
- Adds richness and coats the flour so it blends without clumping.
- Veal stock (in the method)
- Adds savory depth to the liquid base.
The step that matters
Stirring in the flour and butter. Flour clumps when it hits hot liquid unevenly. Rubbing it with butter and stirring it in well lets the starch disperse and thicken smoothly as the soup heats.
