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
- Graham bread
- Forms the thin base and holds the filling together.
- Butter
- Adds fat and richness to the bread, and keeps it from soaking up the dressing.
- Mayonnaise dressing
- Adds moisture and richness that binds the sandwich together.
- Heart lettuce
- Provides crisp texture and fresh moisture between the bread rounds.
The step that matters
Place a leaf of crisp heart lettuce between every two rounds. Lettuce that is wilted or wet will soften the bread and make the sandwich soggy. Using crisp, dry leaves keeps the texture firm.
Swap the lettuce
How well each one fits the dish's main ingredients (bread, butter):
- Leekfits better

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