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 to the sandwich.
Butter
Adds fat and richness and helps keep the bread from soaking up moisture.
Mayonnaise
Adds creaminess, fat and a tangy flavour that binds the filling.

The step that matters

Keep the sandwiches very cold until ready to serve. Mayonnaise is an emulsion that can separate or warm to an unsafe range if left out. Lettuce wilts and loses crispness at room temperature, so chilling keeps both texture and food safety.

Swap the lettuce

How well each one fits the dish's main ingredients (butter, bread):

  1. Leekfits better
  2. Potatofits better
  3. Tomatofits better
  4. Lettucethe original

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