Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Provides the main protein; dredging in flour helps the pieces hold a little coating in the sauce.
- Flour
- Coats the beef and thickens the gravy sauce as it simmers.
- Onion
- Browning in butter builds a sweet, savory base for the curry.
- Butter
- Carries the curry powder's flavor and adds richness to the frying step.
- Gravy
- Supplies the liquid and meaty flavor that forms the curry sauce.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic aroma and flavor.
The step that matters
Adding the curry powder. Curry powder contains aromatic spices that can turn bitter or raw if underused or overcooked, and its strength varies by brand. Starting small and tasting before adding more lets the cook balance heat and flavor without overpowering the beef.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour, butter, meat, rice):
- Potatofits better
