Oh, one more fun recipe to make with shark is what I call "Shark Bites". A restaurant back in NY used to make something similar with swordfish & they were terrific, but I much prefer them with shark (catchier title, too - lol!!).
Anyway, all you do is remove the skin, if present, from the shark steak & cut into bite-size cubes. Then toss the cubes lightly in some flour seasoned with some salt, pepper, paprika, & granulated garlic. Heat some extra-virgin olive oil or half-&-half olive oil & butter in either a cast-iron pan or a wok & pan-fry the shark cubes until lightly browned & cooked through. Serve with lots of lemon wedges.
These can be served as an appetizer - either plated or stuck with toothpicks - or as an entree.
