Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced meat
- Forms the main body of the hash and provides its savory, meaty flavor.
- Gravy from cooked meat
- Adds moisture and rich meat flavor so the mixture stays loose and juicy.
- Vinegar
- Adds acidity that brightens the rich meat and gravy.
- Onion or shallot
- Adds aroma and gentle sweetness as it softens in the water.
- Bread
- Serves as a base that soaks up the gravy and meat juices.
The step that matters
Do not let the meat mixture boil. Once the minced meat and gravy are added, boiling toughens the meat proteins and can make the texture dry and grainy. Keeping the mixture just hot lets it stay tender and moist.
Swap the onion
How well each one fits the dish's main ingredients (pepper, meat, vinegar, bread):
