Ingredients
Directions
Make the filling
Mash the cheese with a silver fork in a bowl.
Mix in the yolks of the hard boiled eggs and enough mayonnaise dressing to season well.

Optionally, add a leaf of lettuce with the cheese between the bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rich cheese
- Provides the main flavor and creamy body of the filling.
- Hard boiled egg yolks
- Add richness and a soft, crumbly texture to the filling.
- Mayonnaise dressing
- Adds moisture and fat, binding the filling and seasoning it.
- Bread
- Provides the structure that holds the filling together.
- Butter
- Adds fat and flavor to the bread and helps keep it from soaking up moisture.
The step that matters
Mashing the cheese and yolks with dressing. Mixing the filling until smooth and evenly seasoned keeps every bite consistent. Adding dressing gradually lets you control moisture so the filling spreads well without becoming runny.
Swap the lettuce
The recipe marks lettuce as optional. How well each one fits the dish's main ingredients (cheese, egg, bread, butter):
- Asparagusfits better
- Potatofits better
- Chivefits better
- Lettucethe original
Fit is the average pairing score against cheese, egg, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
