Why it works: Lettuce and olive match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,580 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ingredients
Directions
Prepare
Toast the slices of bread until golden brown.
While hot, spread butter on one side of each slice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Toasted slices provide a crisp, sturdy structure that holds the layered filling.
- Butter
- Spread on the hot toast, it adds richness and moisture and keeps the bread from soaking up the dressing.
- Cold baked chicken
- Provides the substantial, savory protein that gives the sandwich its body.
- Slices of hot crisp bacon
- Adds salty, smoky crunch that contrasts with the softer layers.
- Salad dressing
- Adds moisture and tang that binds the filling and seasons the chicken and vegetables.
The step that matters
Butter the toast while it is hot. Butter melts into warm, porous toast and coats the surface, forming a light barrier. Spreading it on cold toast leaves it in clumps and lets the dressing and juices soak in, making the sandwich soggy.
Swap the lettuce
How well each one fits the dish's main ingredients (bread, butter, chicken, olive):
- Tomatofits better
- Potatofits better
- Capsicumfits better
- Lettucethe original
Fit is the average pairing score against bread, butter, chicken, olive. Candidates are from the same food group and used in at least 100 recipes.
