Why it works: Butter and onion are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Forms the main body of the stew, becoming tender and rich as it stews slowly.
- Butter
- Adds fat that carries flavour and gives the gravy a richer, smoother mouthfeel.
- Onions
- Release sweetness and savoury aroma into the stewing liquid as they cook.
- Sweet herbs
- Infuse the stewing liquid with aromatic flavour as the meat cooks.
- Red wine
- Adds acidity and depth of flavour to the finished gravy.
The step that matters
Stewing the rolled mutton. Connective tissue in mutton breaks down into gelatin over long, gentle simmering. Boiling hard instead of simmering gently can toughen the meat and leave it stringy.
Swap the onion
How well each one fits the dish's main ingredients (mutton, butter, red wine):
- Tomatofits better
- Potatofits about as well
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against mutton, butter, red wine. Candidates are from the same food group and used in at least 100 recipes.
