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 main meat and rich flavour as it slowly simmers.
- Potatoes
- Thicken the broth as they break down and add body to the stew.
- Carrots
- Add gentle sweetness and colour to the stew.
The step that matters
Simmer gently after boiling. A hard, rolling boil toughens meat fibres and can break up the potatoes, leaving the stew cloudy and uneven. A gentle simmer lets the mutton become tender while the broth stays clear.
Swap the potato
How well each one fits the dish's main ingredients (mutton, carrot, pepper):
- Capsicumfits better
- Turnipfits better
- Parsnipfits about as well
- Potatothe original
Fit is the average pairing score against mutton, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes.
