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

What each ingredient does

Ham
Provides the savory, meaty filling that gives the sandwich its main flavor.
Pickles
Add acidity and a tangy bite that cuts through the rich butter.
Butter
Adds fat and moisture, binding the filling and helping it spread smoothly on the bread.
Bread
Provides the structure that holds the filling and lets the sandwich be pressed and cut.

The step that matters

Beating the butter until creamy. Softened butter beaten until creamy blends evenly with the ham mixture, so the filling spreads smoothly and stays consistent instead of clumping or tearing the thin bread.

Swap the mustard
