  2. 2Harvested wild in a brief spring window before the frond unfurls
  3. 3Must be cooked through (blanched/boiled) — never eaten raw, due to a heat-labile toxin
  4. 4Finished by sautéing in fat, typically butter, with a bright acid or garlic accent
  5. 5Served as a seasonal vegetable, prized for its grassy, asparagus-meets-spinach character
