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 ↓
Corn Soup
Ingredients
Directions
Make the soup base
Mash the corn in a bowl.
Cook the mashed corn with 1 quart of milk for 15 minutes after it reaches boiling point.
In a small pan, cook the butter and onion for a few minutes.
Add the flour to the butter and onion, stirring until smooth.
Stir the butter mixture into the corn and milk.
Add salt and pepper, and cook for an additional 10 minutes.
Finish and serve
Strain the soup, then stir in the well-beaten egg yolks and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid body of the soup and carries the corn flavour.
- Corn
- Provides the main flavour and, when mashed, thickens the soup with starch.
- Butter
- Adds richness and fat, and carries the flavour of the onion.
- Flour
- Thickens the soup by absorbing liquid as it cooks with the butter.
- Egg yolks
- Enrich and thicken the soup when stirred in at the end.
The step that matters
Stirring in the egg yolks. Egg yolks thicken by coagulating when heated. If the soup is too hot when they go in, or they are added without being well beaten, they can scramble or leave streaks. Straining first and adding them off the heat keeps the soup smooth.
Swap the onion
How well each one fits the dish's main ingredients (milk, corn, butter, flour, egg, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against milk, corn, butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
