Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dressed mutton
- Provides the meat that forms the body of the hash.
- Flour
- Coats the meat slices, helping the gravy thicken and cling to them.
- Onion
- Adds savoury flavour and aroma to the hash.
- Gravy
- Supplies moisture and savoury richness that binds the hash together.
The step that matters
Heat the mixture but do not let it boil. Boiling toughens meat proteins and can make the floured coating break up or turn lumpy, so gentle heating keeps the meat tender and the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, pepper, ketchup):
- Turnipfits better
