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

What each ingredient does

Mutton leg: Provides the main cut of meat that becomes tender during long, gentle simmering.
Veal forcemeat: Fills the boned fillet, adding moisture and richness to the meat.
Onions: Add aromatic flavour and sweetness to the cooking liquid.
Carrots: Add sweetness and body to the broth as they soften.
Parsley: Adds a fresh, herbal aroma to the cooking liquid.

The step that matters

Simmer gently for about 2 hours. A gentle simmer keeps the liquid below a boil, so the muscle fibres and connective tissue break down slowly without toughening or drying the meat.
