There are two ways to prepare squid (aka calamari) with succulent results: very quickly, as in searing, grilling, or flash-frying; or very long, as in braising, stewing, or slow-roasting. Anywhere in between will yield rubbery, rigid bands like undercooked cartilage. I went with the latter preparation for this late-winter, almost-springlike, one-seafood stew. It could be plopped on top of pasta, or sopped up with pieces of bread. Tentacles had never been more tender.
