Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Slow stewing breaks down connective tissue, leaving the meat tender and rich.
- Tomatoes
- Provide moisture and acidity that build the body of the stew.
- Butter
- Adds fat for a smooth, rounded mouthfeel and richer flavour.
- Tomato ketchup
- Adds sweetness, acidity and concentrated tomato flavour.
- Ground clove
- Contributes a warm, aromatic spice note.
The step that matters
Stew the beef slowly. Gentle, low-heat simmering lets the connective tissue in the beef soften gradually. Rushing with high heat can leave the meat tough and dry, while slow cooking yields a tender texture and a richer, well-blended sauce.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (tomato, beef, clove, butter, ketchup):
- Capsicumfits better
