Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce leaves
- Provides the crisp texture and fresh moisture that fills the sandwich.
- Slices of bread
- Gives structure, holding the filling together between its slices.
- Butter
- Adds richness and a fatty layer that helps keep the bread from soaking.
- Mayonnaise
- Adds creamy richness and fat that complements the lettuce.
The step that matters
Drying the salted lettuce in the napkin. Salt draws water out of the leaves, and any moisture left on them will soak into the bread and make it soggy. Drying the lettuce before it is layered keeps the sandwich firm and the bread intact.
Swap the lettuce
How well each one fits the dish's main ingredients (bread, butter):
- Leekfits better

- Lettucethe original
Fit is the average pairing score against bread, butter. Candidates are from the same food group and used in at least 100 recipes.
