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

What each ingredient does

Hard boiled eggs
Provide the main body and creamy texture of the sandwich filling.
Green pepper
Adds crisp texture and fresh, slightly bitter flavor to the filling.
Melted butter
Adds fat and richness, helping bind the filling and keep it moist.
Mustard dressing
Adds tang and sharpness that cut through the richness of the eggs and butter.

The step that matters

Mix until well combined to form a paste. Chopped eggs and pepper must be evenly coated with the butter and dressing so the filling holds together and every bite is seasoned consistently. Under-mixing leaves dry pockets and loose pieces that fall out of the bread.

Swap the white pepper

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

  1. Capersfits better
  2. Parsleyfits better
  3. Tarragonfits better
  4. White pepperthe original
