The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: nonanal (fat, citrus).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Adds crisp, fresh texture and moisture-free crunch when kept dry.
- Buttered bread
- Provides the base structure and a rich, fatty layer that carries the filling.
- Mayonnaise
- Can replace butter as the fatty spread, adding richness and a tangy flavour.
The step that matters
Keep the lettuce dry. Surface water from wet lettuce soaks into the bread and makes it soggy. Drying the leaf thoroughly keeps the sandwich crisp and holds the fat layer in place.
