- 3 pounds russet potatoes
- 2 tablespoons white wine vinegar
- 1 1/2 teaspoons dry mustard

- Cover potatoes with salted water in large pot. Cover and boil gently until potatoes are tender but still hold their shape, about 30 minutes. Drain and cool slightly. Peel and cut into 1-inch pieces. Transfer potato pieces to large bowl.
