Layer and stew

  1. Layer potatoes at the bottom of a stewing pan.

  2. Add a layer of mutton and onions; season with pepper and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mutton
Provides the meat and rich flavour that the stew is built around.
Potatoes
Form the base layer and thicken the stew as they break down during slow cooking.
Onions
Add sweetness and aroma as they soften during the long, gentle stew.

The step that matters

Keeping the lid tightly closed while stewing. A tight lid traps steam so the stew cooks gently in its own moisture. Letting steam escape can dry the contents and scorch the bottom, and the occasional shaking helps prevent sticking.

Swap the onion

How well each one fits the dish's main ingredients (mutton, potato, pepper):

  1. Carrotfits better
  2. Capsicumfits better
  3. Tomatofits about as well
  4. Onionthe original

Fit is the average pairing score against mutton, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
