Step 1Peel the potatoes and cut them into 1-inch chunks. Place them in a 4-quart saucepan with water to cover and bring to a boil over high heat. Reduce the heat, cover and simmer until the potatoes are tender, about 15 minutes. Drain.
Step 2In a large bowl, mash the potatoes coarsely, leaving some small chunks, and mix with the mayonnaise, onions, relish, pickle juice, pepper sauce and salt to taste.
