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; browning it first builds savoury flavour and it becomes tender during simmering.
- Butter
- Carries the heat for frying and adds richness to the sauce.
- Onion
- Softens as it fries, adding sweetness and a base layer of flavour.
- Curry powder
- Blooms in the fat with the meat, releasing aroma and warm spice flavour.
- Stock
- Forms the liquid that simmers the beef and turns the spices into a sauce.
- Lemon juice
- Adds acidity that brightens the rich, spiced sauce.
The step that matters
Simmer until the beef is tender. Beef made tough by searing needs long, gentle simmering so collagen breaks down; a hard boil toughens the meat and can dry out the sauce.
