Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fats the pan and carries the curry spices, adding richness to the sauce.
- Onions
- Soften and brown, adding sweetness and depth to the base.
- Curry powder
- Provides the main spice flavour and aroma of the dish.
- Flour
- Thickens the stock into a smooth, body-rich sauce.
- Stock
- Moistens the roux-like mixture and forms the liquid of the sauce.
- Mutton
- Provides the meat, which is gently reheated in the sauce to stay tender.
The step that matters
Add the cooked mutton and simmer until heated through, avoiding boiling.. Mutton is already cooked, so it only needs gentle reheating. Boiling toughens cooked meat proteins and can make the meat dry and stringy.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, mutton, rice):
- Leekfits better
