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

What each ingredient does

Bread
Provides the structure that holds the filling together.
Butter
Adds fat and richness, and creates a barrier that keeps bread from soaking up moisture.
Mayonnaise or vinegar dressing
Adds moisture and tang, and helps flavour the bread.
Crisp lettuce leaves
Supplies crunch and fresh moisture to the sandwich.

The step that matters

Drain the lettuce well. Excess water from washed lettuce soaks into the bread and makes the sandwich soggy. Draining and shredding the leaves before layering keeps the bread firm and the filling crisp.

Swap the lettuce

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

  1. Shallotfits better
  2. Capsicumfits better
  3. Carrotfits better
  4. Lettucethe original

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