Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Browning in the hot fat builds a deep, savoury base for the curry.
- Curry powder
- Provides the main spice flavour and aroma of the curry.
- Apple
- Adds a mild sweetness that softens the sharpness of the spices.
- Meat or chicken
- Supplies the protein that becomes tender during slow simmering.
- Gravy or stock
- Provides the liquid that carries the spices and moistens the dish.
The step that matters
Simmer the mixture until the meat or chicken is cooked through. Simmering gently over low heat lets the meat cook evenly and become tender while the sauce thickens. Boiling hard can toughen meat and make the sauce reduce unevenly, so the heat needs to stay gentle.
Swap the apple
How well each one fits the dish's main ingredients (onion, vinegar, sugar, mushroom, ketchup, milk, meat):
