Why it works: Mutton and onion are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 4,531 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Haunch of Mutton
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and roast
Preheat the oven to 400°F (200°C).
Rub the haunch of mutton with salt.
Roast the mutton in the oven until cooked to your preference.
Serve
Serve with onion sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haunch of mutton
- Forms the main cut of meat, providing the dish's richness and the bulk of the serving.
- Onion sauce
- Adds moisture and a savory, sweet onion flavour to balance the rich meat.
The step that matters
Roasting to the right doneness. Mutton is easy to overcook, which dries out the muscle fibres and toughens the meat. Checking for doneness before the meat is fully cooked lets the juices stay within the cut and keeps it tender.
Swap the onion
How well each one fits the dish's main ingredients (mutton, sauce):
- Shallotfits better
- Tomatofits better
- Onionthe original
- Capsicumfits about as well
Fit is the average pairing score against mutton, sauce. Candidates are from the same food group and used in at least 100 recipes.
