It’s a fairly firm white fish…not quite the texture of tuna, but far more solid than something such as cod. I’ve done it in a Thai-style curry, poaching the shark steaks in the sauce for 15 minutes or so, after which it broke up into chunks.
The best shark steak I ever had was wrapped in a tinfoil packet with some veggies (carrots, cauliflower, and brocoli, IIRC), butter, and little lemon juice, then tossed on the grill.
I’ve only had shark that was poached and the meat always turned out a little rubbery, like calamari. My dad was the one who cooked it, maybe he was doing something wrong?
Probably not doing it gently enough. Make the sauce, then place the meat onto the top, cover and take the heat down to barely-simmering (that’s the technical term )
