Seppie in Umido col Nero di Seppia (Cuttlefish Stewed in Its Ink)

Cuttlefish (Sepia officinalis) is a roughly oval-shaped cousin of the squid, with thicker, sweeter flesh and richer ink—and more of it. Frozen cuttlefish is sold cleaned, with the ink sacs removed. If you use it, you'll need to buy cuttlefish ink separately; use 2-3 tbsp. for this recipe.
