Why it works: Lemon and lettuce match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,559 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: 1-penten-3-one (fish, pungent).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
