If desired, peel the potatoes and slice them to the size you need; whole potatoes may be boiled with the skins on.
Place the potatoes in a medium saucepan and add enough water to cover them (about 1 quart for the amount here).
Stir in 1 tablespoon salt, then heat the pan over high heat until the water is simmering.
Simmer sliced potatoes for about 5–7 minutes, or whole potatoes for about 10 minutes, until a fork pierces them easily to your desired tenderness.
When cooked, pour the contents into a colander to drain off the water.
Return potatoes to a bowl or pan and season with salt and pepper to taste, or use them in your recipe as directed.
