Why it works: Onion and lettuce match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,562 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
- Onions
- Soften and sweeten as they cook down, forming the base of the sauce.
- Lettuce or greens
- Add moisture and body as they wilt into the stew.
- Fowl or mutton
- Provides the meat, whose juices and collagen enrich the thickening sauce.
The step that matters
Stew the mixture slowly until it resembles a thick sauce. Slow, gentle heat lets the onions and meat release juices and break down connective tissue gradually, so the mixture thickens into a sauce rather than scorching or drying out.
Swap the lettuce
