Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and turn golden, adding sweetness and a savory base to the sauce.
- Butter
- Carries the curry flavours and adds richness to the sauce.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic flavour.
- Cornflour
- Thickens the stock into a smooth sauce that clings to the meat.
- Meat
- Becomes tender through slow simmering, forming the body of the dish.
- Lemon juice
- Adds acidity that brightens the rich, spiced sauce.
The step that matters
Mixing curry powder and cornflour into the onions. Spices bloomed in fat release more flavour, but cornflour added to hot liquid can clump. Stirring until smooth before adding stock keeps the sauce even.
Swap the lemon
