Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and 68,474 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Make the wine sauce
Mix 1 dessert spoonful of flour with a little butter and a wineglass of water, the juice of a lemon, salt, pepper and a little nutmeg.
Place the mixture on a quick fire and stir.
When the sauce has boiled up two or three times take off the fire and serve.
Make the pickled vegetables
Chop twelve green peppers, twelve red peppers, and fifteen small onions finely.
Pour the chopped vegetables over boiling water and let stand 5 minutes, then drain.
Again pour over boiling water and let stand 10 minutes, drain, and add 1 cup of sugar, 3 teaspoonfuls salt, and 1 quart of vinegar.
Boil the mixture for 15 minutes and can.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it heats, giving it body.
- Butter (in the method)
- Adds richness and a smooth mouthfeel to the sauce.
- Green peppers
- Provide the main vegetable bulk and a fresh, slightly bitter flavour.
- Red peppers
- Add sweetness and colour to the chopped vegetable mixture.
- Small onions
- Add pungency that mellows during the boiling and pickling.
- Vinegar
- Provides acidity that preserves and sharpens the vegetables.
The step that matters
Boiling the vegetables in water twice before adding vinegar. The two rounds of boiling water soften the chopped vegetables and draw out some of their moisture and sharpness, so they stay tender and balanced once the vinegar mixture is added and boiled.

Fit is the average pairing score against vinegar, flour, pepper. 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).
