makes 5 pounds

5 pounds white or red new potatoes, cut into 1-inch cubes

8 cups water

1 teaspoon kosher salt

sauce:

2 cups mayonnaise (we love Duke's)

1/4 cup white distilled vinegar

1 teaspoon kosher salt

1/2 teaspoon ground black pepper

1 cup finely minced onion

Place the cubed potatoes in a 6-quart stockpot, add water and 1 teaspoon of kosher salt; bring to a boil and cook until fork tender. Drain and cool potatoes completely. In a large bowl, whisk together mayonnaise, vinegar, onion, salt, and pepper. Pour over cooled potatoes; gently mix and garnish if desired. Refrigerate leftovers.
