Potato salad is one of the few recipes where the technique actually matters more than the ingredient list. The difference between okay potato salad and holy crap who made this” potato salad is the doneness of the potatoes and seasoning while warm. Seasoning the potatoes while they’re still steaming and before the mayo dressing goes on makes the potatoes taste seasoned all the way to the center instead of tasting like bland chunks under a nice dressing. Tiny detail, massive effect.
