Add eggs to a saucepan and cover eggs with cold water. Heat until water comes to a boil. Boil the eggs for 12 minutes. Remove eggs to an ice water bath to cool.
Slice the peeled eggs in half, lengthwise. Carefully remove the yolks and place them in a separate bowl.
Mash the egg yolks with a fork, then add mayonnaise, mustard, salt and white pepper. I use about 1/8th a teaspoon of salt and only a sprinkle of white pepper, but you can adjust it to your taste.
Spoon or pipe the filling back into the egg whites.
