Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat from mutton or lamb
- Provides the main savoury flavour and the bulk of the hash.
- Bones from mutton or lamb
- Stewing the bones in water releases flavour and gelatin into the liquid, enriching the sauce.
- Browned flour
- Thickens the liquid and adds a toasted, nutty depth of flavour.
- Ketchup
- Adds sweetness and acidity that balance the rich meat.
- Capers
- Add a sharp, briny accent that cuts through the richness.
The step that matters
Thicken the water with browned flour. Flour must be added to hot liquid in a way that avoids lumps; whisking it in smoothly and simmering lets the starch swell evenly and thicken the sauce properly.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, mutton, flour, ketchup, capers):
- Shallotfits better
- Turnipfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against meat, mutton, flour, ketchup, capers. Candidates are from the same food group and used in at least 100 recipes.
