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

What each ingredient does

Mutton slices
Provide the main meat, which becomes tender through long stewing in the sauce.
Onion slices
Soften and sweeten as they fry, adding savoury depth to the sauce.
Thick brown sauce
Supplies the moisture and rich flavour that the mutton absorbs during stewing.
Mashed turnips
Form a soft, mild border that contrasts with the rich, saucy meat.

The step that matters

Browning the mutton rounds in hot dripping. Frying in hot fat browns the surface through the Maillard reaction, creating deep savoury flavour that carries into the stewed sauce. Pale, under-browned rounds will taste flat.

Swap the turnip

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