Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Underdone beef
- Provides the main meat texture, which is finely shredded so it becomes tender in the gravy.
- Fat from beef
- Adds richness and moisture to the minced meat as it cooks.
- Onion
- Softens while boiling, adding sweetness and savoury body to the mixture.
- Vinegar
- Adds acidity that brightens the rich, savoury flavour of the beef.
- Ketchup
- Adds sweetness and tang, rounding out the savoury flavour.
The step that matters
Boil until the onion is soft. The onion must cook fully so it softens and blends into the gravy. Undercooked onion stays sharp and crunchy, which spoils the smooth texture of the minced beef.
Swap the onion
