boiled potatoes- you tube videos, my favourite is Chef John @ all recipes.com

Peel potatoes, I allow 2 per person

cover potatoes with cold water (they grow below ground) , cover with a lid and check with a fork.  Fork tender they are ready to strain and mash.  I add butter and milk.  Some add sour cream, cream cheese, chicken stock - go with  your favourite.  Salt and pepper while mashing.
