Boil three eggs in a saucepan of water for 10 minutes.

Place immediately the eggs in cold water so that you can peel the shells easily.

Peel the eggs and place the peeled eggs in a bowl.

Break up and fluff the eggs with a fork.

Add salt, sugar, milk, mayonnaise and pepper and adjust seasoning if necessary.

Now butter two sandwich slices and add the egg salad and topping them using the two other slices. Press down carefully and evenly so that you don't spill any salad on the sides of the sandwiches.

Using a sharp knife, trim the edges of the sandwiches and cut the sandwiches in half.
