Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fowl, with Onions
Ingredients
Directions
Prepare
Pluck, draw, singe, and wash the fowl, then truss it as if for boiling.
Rub a saucepan with butter and place the fowl inside with the white broth.
Smear the fowl with more butter.
Season the fowl with pepper and coarse sea salt.
Stew
Stew gently for 30 minutes.
Add the small onions.
Continue to stew for another 30 minutes.
Turn the fowl three or four times during cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main protein, which becomes tender through gentle, slow stewing.
- White broth
- Supplies moisture that keeps the fowl from drying out while it stews.
- Butter
- Adds fat that carries flavour and helps the fowl's skin brown and enrich the dish.
- Small onions
- Soften during stewing and add sweetness and aroma to the cooking liquid.
The step that matters
Stew gently for 30 minutes. Keeping the heat low and the liquid barely simmering lets the connective tissue in the fowl break down slowly, so the meat stays tender instead of tough and dry.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
