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, which is cooked gently and finely shredded for the texture of the dish.
- Fat
- Adds richness and moisture to the minced beef.
- Onion or shallot
- Adds savoury flavour and softens during boiling.
- Vinegar
- Adds sharpness that balances the richness of the meat and fat.
The step that matters
Add the minced beef without boiling. Once the meat is added to the hot gravy, boiling can toughen the proteins and make the mince dry and grainy. Keeping it just below a boil keeps it tender and moist.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, vinegar, bread):
- Capsicumfits better
- Tomatofits better
- Onionthe original
- Mustardfits about as well
Fit is the average pairing score against beef, pepper, vinegar, bread. Candidates are from the same food group and used in at least 100 recipes.
