Ingredients
Directions
Prepare the eggs
Boil fresh eggs for 5 minutes, then peel them.
Remove a little white from each end and cut the eggs into 4 slices.
Assemble the sandwiches
Chop the boiled eggs finely and mix with butter, salt, and pepper.
Spread the mixture on buttered slices of bread and assemble the sandwiches.
For variety, mix in a little chopped ham.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main filling, setting firm when boiled and holding the sandwich together.
- Butter
- Adds fat and richness, giving the chopped egg filling a smooth, moist texture.
- Bread
- Provides the structure that holds the filling and carries it to the mouth.
The step that matters
Boil fresh eggs for 5 minutes, then peel them.. Boiling for the right time sets the yolks fully without overcooking them, which avoids a dry, grey-rimmed filling that is harder to chop and spread.
