Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Melts to form a fat base that carries the curry flavour and softens the onion.
Flour
Thickens the milk into a smooth sauce as it cooks.
Curry powder
Provides the main spiced aroma and flavour of the sauce.
Milk
Forms the liquid base of the sauce, which thickens as it simmers.
Prawns
Provide the main protein and mild sweetness in the finished curry.

The step that matters

Adding the milk to the flour. Adding liquid gradually while stirring helps the flour disperse evenly, preventing lumps and giving a smooth sauce before it is brought to a boil.

Swap the onion

How well each one fits the dish's main ingredients (butter, flour, milk, lemon, rice):
