Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef rump steak
- Is the main protein, becoming tender through gentle covered cooking after marinating.
- Vinegar
- Acidity in the marinade helps loosen the beef's surface and adds a sharp, bright note.
- Onion
- Softens and sweetens during frying, forming the base of the sauce and adding savoury depth.
- Mustard seed
- Adds a pungent, nutty aroma when cooked in hot oil.
- Cinnamon stick
- Infuses the oil with warm, sweet aroma during frying.
- Stock
- Adds liquid to the pan, creating a savoury sauce that coats the beef and onions.
The step that matters
Cover the pan and cook over a low heat until the beef is tender. Rump steak is a lean cut that toughens if cooked hard and fast. Gentle, covered heat with some moisture lets connective tissue break down slowly, keeping the slices tender rather than dry and chewy.
Swap the curry leaf
How well each one fits the dish's main ingredients (beef, onion, vinegar, pepper, cinnamon, mustard, sugar):
- Allspicefits better
