Key to success: Dry the arugula thoroughly — trapped water is the enemy. Supreming the citrus takes 90 seconds and makes the salad look restaurant-level. Do not dress the arugula in advance; once dressed, eat within 30 minutes. For make-ahead, keep citrus and dressing together in one container, shallots separate, and arugula dry in a paper towel-lined bag. Layer and toss just before serving. The flaky salt at the end is not optional — it adds texture and makes the whole thing feel intentional.
