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 a crisp, fresh texture and bulk inside the sandwich.
- Salad dressing
- Adds moisture and tangy flavour that keeps the filling from drying out.
- Bread
- Forms the structure that holds the filling together.
- Butter
- Adds richness and a fat barrier that helps keep the bread from soaking through.
The step that matters
Spread the dressing over the lettuce. Using a thicker dressing matters because a thin one soaks into the bread and makes it soggy. The lettuce should be dry and crisp so the sandwich holds together and stays fresh until served.

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