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 ↓
Celery Soup
Ingredients
Directions
Make the stock
Boil the veal bone in 1 quart of water, skimming well.
Add the rice, celery, celery salt, and onion.
Boil until reduced to 1 pint.
Remove the meat and pass the soup through a colander, mashing to extract as much puree as possible.
Thicken and serve
Boil 1 quart of milk separately.
Rub the flour into the butter, then add this mixture to the boiled milk.
Cook for a few minutes, then mix the milk with the celery puree and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk as it cooks, giving the soup a smooth, body-rich texture.
- Butter
- Carries the flour so it blends smoothly into the milk and adds richness.
- Milk
- Forms the creamy base of the soup and adds mild sweetness and body.
- Celery
- Provides the main flavour and, once pureed, the bulk of the soup.
- Rice
- Adds body and helps thicken the stock as it boils down.
The step that matters
Rub the flour into the butter, then add to the milk. Flour added directly to hot liquid clumps, because its starch grains swell on the outside before the inside hydrates. Coating the flour in fat first separates the grains so the milk thickens smoothly.
Swap the celery
How well each one fits the dish's main ingredients (veal, rice, onion, milk, flour, butter):
- Turmericfits better
- Cinnamonfits better
- Capersfits about as well
- Celerythe original
Fit is the average pairing score against veal, rice, onion, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
