Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lettuce
Provides the crisp, fresh bulk and texture of the filling.
Cucumber
Adds cool moisture and a light, crunchy texture to the filling.
Mayonnaise sauce
Binds the vegetables together and adds fat and richness to the filling.
Stale bread
Forms the sturdy outer layers that hold the filling without becoming soggy.
Butter
Coats the bread, adding richness and a barrier against moisture from the filling.

The step that matters

Dry the shredded lettuce thoroughly. Excess water on the leaves dilutes the mayonnaise and soaks into the bread, making the sandwiches soggy. Drying the lettuce keeps the filling thick and the bread firm.

Swap the cucumber

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

  1. Shallotfits better
  2. Mustardfits better
  3. Capsicumfits better
  4. Cucumberthe original

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