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 and substance, becoming tender during slow stewing.
- Tomatoes
- Form the sauce base, releasing liquid and acidity that flavour the stew.
- Sugar
- Balances the acidity of the tomatoes with a mild sweetness.
- Butter
- Adds fat and richness to the finished sauce.
The step that matters
Stew the mixture very slowly. Low, gentle heat lets the beef's connective tissue break down slowly into tenderness without toughening the meat. Rapid boiling tends to firm up the muscle fibres and can scorch the tomatoes and sugar on the base of the pot.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (beef, sugar, clove, butter, ketchup, onion):
- Leekfits better
- Capsicumfits better
- Chivefits better
- Tomatothe original
