This is a family favorite. My grandfather started making for my dad when he was a little boy- a Norwegian dish that always pleases the whole family and leaves us begging for more. I realize that it may be confusing that there are no amounts listed. This is a "to taste" recipe. And the amounts are equal if you have a 3 lb roast then you use 3 lbs of potatoes. When mashing them together add milk/pot liquor to your preference of consistency. Also the seasonings you add should be to your taste i.e. garlic, salt, pepper, butter or other spices YOU like. Adapt this recipe to your taste and make it YOUR dish! I am now making amounts for those who are totally confused.
