Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main protein; its connective tissue softens into tenderness during simmering.
- Butter
- Adds fat that carries flavour and helps the onion and meat brown in the pan.
- Onion
- Softens and turns sweet when fried, building a flavour base for the curry.
- Curry powder
- Supplies the spice aroma and flavour that defines the dish.
- Stock
- Supplies the liquid that moistens the meat and forms the sauce as it simmers.
- Lemon juice
- Adds acidity that brightens the rich, spiced flavours of the curry.
The step that matters
Simmer until the beef is tender. Beef becomes tender only after its connective tissue breaks down over long, gentle simmering. Cooking too fast or stopping too early leaves the meat tough and chewy.
