Why it works: Onion and ginger are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 7,595 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Softened in butter, they build the sweet, savoury base of the sauce.
- Flour
- Thickens the liquid as it heats, giving the sauce body.
- Butter
- Carries the frying onions and adds richness to the sauce.
- Curry powder
- Supplies the main spice flavour and aroma of the sauce.
The step that matters
Adding the cold liquid slowly. Adding cold water or stock gradually while stirring keeps flour from clumping. Lumps form when liquid is poured in quickly, so the sauce stays smooth as it thickens.
Swap the ginger
How well each one fits the dish's main ingredients (onion, butter, flour, meat):
- Capersfits better
- Garlicfits better
- Thymefits better
- Gingerthe original
Fit is the average pairing score against onion, butter, flour, meat. Candidates are from the same food group and used in at least 100 recipes.
