To boil yams on the stove, wash the yams with cold water and peel them with a vegetable peeler or a paring knife. Trim off the ends of the yams and cut them into bite-sized cubes. Fill a pot halfway with water and add a pinch of salt, then bring the water to a boil over high heat. Add the yams to the pot and cover it, then reduce the heat a bit so it doesn’t boil over. Cook the yams until they are tender and easy to pierce with a fork, which should take 10-15 minutes. Remove the pot from the heat and pour the yams into a colander to drain them. Toss the yams in butter, salt, and pepper, add any other seasonings of your choice, and serve them warm. For tips on how to make mashed yams on the stove, keep reading!
