I use any potato I find handy, even yams. Peel the skin, cut in cubes so it will cook faster.( slide a fork in the potato and it should go in easy but not mushy.) Drain the water from the pot. I use sour cream and butter in place of milk. Whip with beater until it is the texture you like. Salt and pepper. You can add garlic to the water when cooking the potatoes also. So many different flavors can be added. Hope this gave you some ideas.
