Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roasted mutton
- Provides the main body and meaty bulk of the dish.
- Butter
- Adds fat and richness while softening and browning the onions.
- Gravy
- Supplies moisture and savoury flavour that keeps the hash from drying out.
- Walnut ketchup
- Adds deep, salty, tangy savouriness to the sauce.
- Lemon pickle
- Contributes sharp acidity that brightens the rich meat and gravy.
The step that matters
Stew the gravy before adding the mutton. Letting the gravy simmer concentrates its flavour and thickens it slightly, so the sauce coats the meat instead of thinning out into a watery mixture.
Swap the cabbage
How well each one fits the dish's main ingredients (mutton, butter, walnut, ketchup, lemon, pepper):
- Capsicumfits better
- Shallotfits better
- Spinachfits better
- Cabbagethe original
Fit is the average pairing score against mutton, butter, walnut, ketchup, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
