Place the potatoes in a large pot and pour enough water to cover them by about one to two inches. Add about 1 tablespoon of salt to the water. Heat the pot over medium-high heat until the water boils, then lower the heat to medium-low, cover the pot, and allow the potatoes to simmer for around 10 to 15 minutes until they are cooked all the way through but not too soft. Test them by piercing them with a knife to make sure they are tender but not mushy.
