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 ↓
Shoulder of Mutton Roasted
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 350°F (175°C).
Prepare the shoulder of mutton by trimming excess fat if necessary.
Place the shoulder in a roasting pan and season with salt.
Roast and serve
Roast in the oven, basting occasionally, until cooked to your liking.
Serve with onion sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shoulder of mutton
- Provides the main meat; its fat renders during roasting, keeping the meat moist and flavourful.
The step that matters
Roast until cooked to your liking. Meat keeps cooking after it leaves the oven, and overcooking dries out the fibres. Basting adds moisture to the surface while the fat renders, so checking doneness during roasting helps avoid a dry shoulder.
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.
