Ingredients

Directions

Prepare

  1. Cut the mutton into tidy chops, removing excess fat.

Layer and cook

  1. In a large saucepan, layer sliced potatoes, onions, and chops, seasoning each layer with pepper and salt. Ensure the potatoes are on top, then add cold water until just visible.

  2. Bring the stew to a boil, skim off any foam, then reduce heat and simmer for 2 hours.

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

What each ingredient does

Neck of mutton
Provides the meat and fat that flavour the stew as it simmers.
Potatoes
Soften during the long simmer and thicken the broth as their starch releases.
Onions
Break down during simmering, adding sweetness and body to the broth.

The step that matters

Skimming the foam after boiling. Foam carries impurities and fat that would cloud the broth and taste greasy. Skimming before reducing the heat keeps the stew clear and clean-flavoured.

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.
