Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mutton
- Provides the main meat, which is cut fine so it heats evenly in the gravy.
- Gravy
- Supplies the liquid and savoury flavour that moistens the minced meat.
- Catsup
- Adds sweetness and tang that balance the savoury gravy.
- Butter
- Adds fat for richness and a smoother mouthfeel in the sauce.
- Flour
- Thickens the gravy as its starch swells when heated in liquid.
The step that matters
Thicken with flour mixed in water. Flour added dry clumps and stays lumpy. Mixing it into cold water first makes a smooth slurry, which should be stirred into the simmering liquid and cooked briefly so the starch swells and thickens evenly.
Swap the potato
How well each one fits the dish's main ingredients (mutton, butter, flour):
- Leekfits better
- Shallotfits better
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against mutton, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
