Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cream of Salmon
Ingredients
Directions
Prepare the salmon and eggs
Boil the salmon in salted water until soft, then chop it finely.
Hard-boil the eggs, mash the yolks, and press them through a strainer.
Make the soup
In a pot, combine the egg yolks with the butter and flour, then soften with ½ pint of soup stock.
Add pepper and salt, bring to a boil, and stir until smooth.
Add 1 quart of soup stock, bring to a boil again, and strain the mixture.
Stir in the chopped salmon and serve with toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main flesh and flavour of the soup once cooked and chopped.
- Egg yolks
- Mashed and strained, they enrich the soup and give it a smooth, creamy body.
- Butter
- Adds richness and fat, contributing to a smooth mouthfeel.
- Flour
- Thickens the soup when cooked with butter and liquid, giving it body.
- Soup stock
- Forms the liquid base that carries the flavour and dissolves the thickened mixture.
The step that matters
Bringing the thickened mixture to a boil and stirring until smooth. Flour thickens only when its starch is heated in liquid, and stirring prevents lumps from forming as it sets. Stopping the stirring or skipping it lets clumps form in the soup.
