Wash and peel the carrots and cook them in as little boiling, salted water as possible until they are tender. Drain, reserving the liquid for later use in soups, gravies, and the like.
Now pretend the carrots are potatoes and mash them in exactly the same way, adding as little milk a necessary to make them light and fluffy.
Season to taste with salt and pepper, turn out into a serving dish and top with butter or margarine.
