Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh butter
- Carries the onions and adds richness and flavour to the base.
- Onions
- Soften and turn golden as they sauté, adding sweetness and depth to the curry.
- Gravy
- Supplies the liquid and savoury body that the curry base is built on.
The step that matters
Sautéing the onions until golden brown. Onions cooked slowly until golden develop sweetness and deep flavour through browning. Stopping early leaves them sharp and pale, weakening the base.
Swap the onion
How well each one fits the dish's main ingredients (butter, veal):
- Onionthe original
- Leekfits about as well
- Potatofits about as well
- Shallotfits less well
Fit is the average pairing score against butter, veal. Candidates are from the same food group and used in at least 100 recipes.
