Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 81,283 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
Prepare and cook
Cut up 12 large onions.
Boil them in 3 quarts of milk and water equally mixed.
Add meat and thicken
Put in a piece of fowl, or veal, and a piece of bacon with pepper and salt.

Serve
Take out meat and serve it up with toasted bread cut in small pieces in the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Provides the liquid base and richness for the soup.
- Fowl
- Flavors the broth as it simmers.
- Bacon
- Adds savory fat that seasons the broth.
- Butter
- Adds fat and, mixed with flour, helps thicken the soup.
- Onions
- Break down into a pulp, giving body and sweetness to the soup.
The step that matters
Thickening with the butter and flour mixture. Flour must be worked smoothly into the butter before it goes into the hot liquid. Starch thickens as it heats, so unblended flour added to simmering soup tends to form lumps instead of a smooth, even body.

Fit is the average pairing score against milk, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
