Why it works: Pepper and onion 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 ↓

Prepare
Boil a leg of mutton and reserve the cooking liquid.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Thickens the broth as its starches swell in the hot liquid, giving body.
- Leg of mutton
- Releases flavour and gelatin into the cooking liquid, giving the broth its savoury base.
- Onions
- Add sweetness and aromatic depth as they soften into the broth.
The step that matters
Forming the oatmeal paste. Adding oatmeal directly to hot liquid can clump into lumps. Mixing it first with a little liquid to a smooth paste lets the starch disperse evenly, so the broth thickens smoothly.
