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 loin (in the method)
- The main meat, whose connective tissue softens into tenderness during long stewing.
- Pyroligneous acid
- Adds a smoky, savoury flavour to the gravy.
- Butter
- Adds fat, richness and a smoother mouthfeel to the gravy.
- Onions
- Soften during stewing, adding savoury sweetness and aroma to the liquid.
- Red wine
- Adds acidity and depth of flavour to the finished gravy.
- Sweet herbs
- Infuse the stewing liquid with aromatic flavour.
The step that matters
Stew for nearly four hours. Long, gentle stewing breaks down the connective tissue in mutton loin, which makes the meat tender. If the stew is cut short or boils hard, the meat can stay tough and the gravy can turn cloudy or greasy.
Swap the onion
How well each one fits the dish's main ingredients (butter, red wine):
- Tomatofits better
- Potatofits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against butter, red wine. Candidates are from the same food group and used in at least 100 recipes.
