Classic Southern Potato Salad

The recipe for this Southern classic came from the chef Millie Peartree's mother, Millie Bell. The sweet relish melds with the creamy potatoes for a deep, balanced flavor. Onion powder adds savory notes without the texture of diced onion, which could overpower the dish. Make sure that your eggs are rinsed thoroughly, so no pieces of shell remain, and that your potatoes are uniformly cut in roughly 1-inch cubes so they all finish cooking at the same time. (Millie Bell used her thumb as a measure.) And, most important of all, don't overcook the potatoes -- they take only 15 to 20 minutes to boil. You want potato salad, not mashed potatoes. You can prepare potato salad ahead of time and refrigerate it for up to 4 days.
