Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which cooks quickly in thin slices and gives the dish its body.
- Flour
- Coats the slices so the cooking liquid thickens slightly and clings to the meat.
- Onion
- Softens in the simmering liquid, adding sweetness and savory aroma to the sauce.
- Broth or water
- Provides the cooking liquid that keeps the meat moist and carries the flavors.
- Harvey sauce
- Adds a tangy, savory depth that seasons the meat and the liquid.
The step that matters
Boil together for three minutes. Thin mutton slices cook in very little time. Boiling them longer tightens the proteins, making the meat tough and dry.
Swap the onion
How well each one fits the dish's main ingredients (mutton, flour, pepper, sauce):
- Shallotfits better
- Capsicumfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against mutton, flour, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
