Perfecting a crab salad begins with perfecting the ingredients, and yes, every single thing counts. Fresh, succulent crab meat should be matched with a dressing that complements its flavors well, and more often than not, it's mayonnaise's distinctive tang that highlights the seafood's natural sweetness. But if you want to take it to the next level, ditch your regular mayo, as kewpie mayonnaise can do an even better job. With more boldness and charm, this staple Japanese condiment is perfect for this dish.
