Why it works: Lettuce and onion 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
- Bacon or ham
- Renders fat that carries flavor and adds savory, crisp, browned bits to the dish.
- Vinegar
- Adds acidity that sharpens the flavor and helps offset the richness of the fat.
- Lettuce
- Forms the base of the dish, softening as the hot mixture is poured over it.
The step that matters
Pouring the hot mixture over the lettuce. The hot bacon fat and vinegar wilt the leaves almost on contact. If the mixture cools first, the lettuce stays crisp and the dressing will not coat it well.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (ham, vinegar, lettuce):
- Mustardfits better
- Cucumberfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against ham, vinegar, lettuce. Candidates are from the same food group and used in at least 100 recipes.
