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 ↓
Cream of Salmon Soup
Ingredients
Directions
Prepare the salmon and milk
Drain the oil from the salmon, remove bones and skin, and mash the salmon finely.
Heat 1 cup of the milk and strain it through a sieve or vegetable press.
In a double boiler, heat the remaining milk.
Make the soup
Rub the butter and flour together, then add to the scalded milk and stir for a moment.
Add salt and cayenne, then stir in the strained salmon.
Heat well and serve.
For a pink color, add a drop or two of red food coloring.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup, giving it its body and creamy character.
- Butter
- Adds richness and fat, carrying flavor and smoothing the texture of the soup.
- Flour
- Thickens the milk as it heats, giving the soup a smooth, body-rich texture.
- Salmon
- Provides the main flavor and protein, mashed so it blends into the creamy base.
The step that matters
Adding the butter and flour to the scalded milk. Flour must be fully blended into the fat before it meets hot milk, and the mixture stirred, or it clumps instead of thickening smoothly. Heating the milk in a double boiler keeps it from scorching and curdling.
