Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Underdone beef
- Forms the main body of the dish and carries its meaty flavour.
- Fat
- Adds richness and moisture to the minced meat.
- Onion or shallot
- Softened by boiling, it adds sweetness and savoury depth.
- Vinegar
- Added at the end, it contributes sharpness that balances the rich meat.
The step that matters
Heat without boiling. Boiling the minced meat after adding it can toughen the protein and make it dry and grainy. Gentle heating keeps it tender and moist.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, vinegar, bread, meat):
- Capsicumfits better
