Egg Sandwiches

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the filling

Boil the eggs until hard, about 10 minutes.
Peel and chop the eggs finely.
Mix the chopped eggs with butter, salt, and pepper to taste.

Assemble and serve

Spread the egg mixture on slices of bread.
Cut the sandwiches into quarters and serve.

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

What each ingredient does

Eggs: Form the main filling, setting firm when boiled and then chopped.
Bread: Provides the base that holds the filling in a sandwich.
Butter: Adds fat and richness, making the chopped egg mixture softer and creamier.
