Why it works: Onion and pepper 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 ↓

Ingredients
Directions
Make the curry sauce

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fowl
- Provides the main cooked meat, which becomes tender as it warms in the sauce.
- Onions
- Browning in butter builds sweetness and depth for the sauce base.
- Butter
- Carries the frying of the onions and adds richness to the sauce.
- Flour
- Thickens the gravy so the sauce clings to the fowl.
- Curry powder
- Supplies the spiced aroma that defines the sauce.
- Gravy
- Forms the liquid base that carries the flavours and moisture of the sauce.
The step that matters
Stewing the sauce with the fowl. Stewing for 30 minutes lets the flour thicken the gravy and the spices mellow. Adding the fowl only to warm it through keeps the meat from toughening, so heat should stay gentle once the joints go in.
Swap the mace
How well each one fits the dish's main ingredients (onion, apple, butter, pepper, vinegar, flour, sugar):
- Cinnamonfits better
- Tarragonfits better
- Clovefits better
- Macethe original
Fit is the average pairing score against onion, apple, butter, pepper, vinegar, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
