Inspired by Thai ajad, a pickled cucumber relish usually served with satay, this dressing is a fever dream of flavor. The complete lack of fat in the sauce brings clarity and sharpness to the balance of salt-sweet-heat-acid. The vegetables become softer and more pickle-y the longer they sit, so make the dressing no more than an hour ahead for optimal potency and crunch. The sauce is excellent over any grilled meat, like chicken, pork chops, or steak, alongside fresh summer rolls, or atop a bowl of warm rice with a crispy fried egg.
