You know what seafood I find just about irresistible? Canned octopus. There are good brands and mediocre brands, but I've never had a bad one.
Take this very inexpensive brand, Del Sol, which is produced in Spain. It's amusingly labeled in both Spanish and English: Pulpo a la Marinera / Octopus in Marine Sauce. Heh.
Anyway, the moist cooking-in-the-can process that pasteurizes and seals the can isobviously an excellent way to prepare octopus, because just like every other tinned octopodes I've tried, the meat is tender yet firm, somewhat al dente, and just a bit resistant to chewing (but not at all rubbery.) The sauce was nothing special - very oily, not much of a tomato flavor (not much of any flavor, actually) but still carrying a subtle hint of spiciness that complimented the meat. Most remarkable of all to me was how very much this octopus reminded me of lobster. No kidding, it had about the same level of chewiness as chunks of lobster tail, and the flavor was similar as well, though not exact. I bet if I had rinsed some of the sauce off, pounded the chunks of meat to "loosen" them up a little, and dressed the bits in mayo, they'd have made a decent Mock Lobster Roll.
Normally, tinned octopus is cut into slices before being packed. I think that someone on the packing line dropped their knife as this can rolled by their work station. Pretty awesome, no?
