Why it works: Butter and white wine are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 5,083 recipes mention both. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Oyster Soup
Ingredients
Directions
Make the broth
Place the shin of veal in a pot with 3 quarts of water, 2 chopped onions, pepper, and salt.
Boil for 3 hours, then strain through a sieve.
Finish and serve
In a separate bowl, mix ¾ pound of butter with 3 tablespoons of flour until smooth, then stir the butter-flour mixture into the strained broth and bring to a boil.
Add the cleaned oysters and 1½ cups of white wine to the pot, bring to a boil again, and serve very hot.

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the broth with fat and body, giving the soup a rich, smooth mouthfeel.
- Flour
- Thickens the broth when cooked with butter, giving it a smoother, heavier body.
- Oysters
- Provide the main briny, savory flavor of the soup.
- White wine
- Adds acidity and brightness that balances the rich butter and savory broth.
- Shin of veal
- Releases gelatin and savory flavor into the water during long boiling, building the broth.
The step that matters
Stirring the butter-flour mixture into the broth. Flour must be cooked to thicken smoothly; if it is added unsmoothed or the mixture is not brought to a boil, lumps and a raw starchy taste can remain.
Flavor stand-ins for the onion

Fit is the average pairing score against veal, egg, pepper, butter, flour, oyster, white wine. 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).
