Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat that is cut into thin collops and cooked through in the sauce.
- Butter
- Adds richness and fat, and helps the collops brown lightly in the pan.
- Flour
- Thickens the gravy into a smooth, cohesive sauce when cooked with butter.
- Walnut ketchup
- Adds a deep, savoury flavour to the sauce.
- Gravy
- Supplies the liquid base of the sauce, carrying flavour and moisture to the meat.
The step that matters
Simmer until done. Thin collops cook quickly, so overcooking toughens the meat and dries it out. Stop once it is just cooked through, since it keeps cooking in the hot sauce.
Swap the walnut
How well each one fits the dish's main ingredients (mutton, ketchup, sauce, pepper, shallot, flour, butter):
- Chestnutfits better
- Beansfits about as well
- Walnutthe original
- Almondfits about as well
Fit is the average pairing score against mutton, ketchup, sauce, pepper, shallot, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
