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 ↓
Cream of Salmon Soup
Ingredients
Directions
Prepare the salmon
Drain oil from the salmon, remove skin and bones, and rub through a sieve.
Make the soup
Gradually add hot milk to the salmon mixture, stirring to combine.
In a separate pan, melt the butter and stir in the flour to make a roux.
Slowly add the salmon and milk mixture to the roux, stirring constantly until smooth.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main body and flavour of the soup.
- Butter
- Adds richness and carries flavour in the roux.
- Flour
- Thickens the soup as it cooks in the butter and liquid.
- Milk
- Forms the creamy liquid that gives the soup its smooth texture.
The step that matters
Slowly add the salmon and milk mixture to the roux, stirring constantly until smooth.. Flour starch swells when heated in liquid, so adding liquid slowly while stirring spreads the starch evenly and prevents lumps.
“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.
