2 lb Potatoes (6 medium)
1/2 lb Butter
Salt and Pepper to taste
1    Minced onion (optional)

Cook potatoes till tender, drain well. Add butter, salt and pepper, onion
and mash. When mixture is cool it is ready to use.
Note: You may wish to combine cheese, or sauerkraut with potatoes; if so,
it is best to combine 2/3 mashed potatoes to 1/3 other ingredients.
