Peel your potatoes and keep a pot with enough water to boil.
Cut your potatoes into four and carefully place potatoes into boiling water.
Boil potatoes over medium to high heat, semi-covered for about 10-15 minutes or until cooked through.
Strain cooked potatoes.
If potatoes are hot, place into a serving dish with the butter, salt, black pepper, and freshly chopped parsley and combine.
If potatoes are cold or cooled, place potatoes into a frying pan with the butter and heat up. Coat potatoes with butter and take from heat. Season with pepper, salt and garnish with chopped parsley.
