Why it works: Lettuce and tomato are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,655 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hamburger
4–6 burgersIngredients
Directions
Prepare the patties
Shape the ground beef by hand into burger patties, yielding 4–6 burgers from 500 g of beef.
Season the outside or mix optional ingredients into the beef before forming the patties; avoid overworking the meat.
Cook and serve
Pan-fry or grill the patties for about 4–5 minutes on each side; ensure they are fully cooked, cutting open if thick to check doneness.
Let the burgers rest for several minutes before serving to allow juices to settle.
Serve each burger on a bun, optionally with relish, sliced pickles, ketchup, mayonnaise, mustard, ranch dressing, cheese, lettuce, tomatoes, and/or onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the meat structure and fat that give the burger its juiciness and savory flavor.
- Hamburger bun
- Holds the patty and adds soft texture that contrasts with the browned meat.
The step that matters
Avoid overworking the meat. Overmixing or overhandling ground beef develops a firm, springy texture in the proteins, making the patty tough rather than tender.
Swap the lettuce
The recipe marks lettuce as optional. How well each one fits the dish's main ingredients (beef, cheese, tomato, onion):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Lettucethe original
Fit is the average pairing score against beef, cheese, tomato, onion. Candidates are from the same food group and used in at least 100 recipes.
