Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat and fat that flavour the dish and the gravy.
- Cold water
- Combines with the rendered juices to form the gravy once the fat is removed.
- Onion
- Adds aromatic sweetness and body to the gravy during stewing.
The step that matters
Skim the fat off the top. Fat that is not removed after cooling stays on the surface and makes the gravy greasy. Chilling lets the fat solidify so it lifts off cleanly.
