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

What each ingredient does

Leg of mutton
Main meat; slow simmering softens its connective tissue and enriches the broth.
Veal forcemeat
Fills the boned cavity, adding moisture and a soft, binding texture to the slices.
Onions
Add aroma and savoury sweetness to the cooking liquid.
Carrots
Sweetness and body in the broth that later becomes the gravy.
Turnips
Mild sweetness and earthy flavour that rounds out the broth.

The step that matters

Simmer gently, do not boil hard. Vigorous boiling toughens the muscle fibres and can break the meat apart. Gentle heat lets connective tissue slowly soften into gelatin, leaving the meat tender and the broth rich.

Swap the onion

How well each one fits the dish's main ingredients (mutton, veal, parsley, carrot, turnip):
