Is there anything you could compare it to, for people who haven't had the chance? I'm vaguely aware the postwar British government promoted corned whale meat an unrationed alternative to normal meats, and that it (unsurprisingly) tasted quite like corned beef.

It tastes like a good steak, just with more umami and tenderness and perhaps a slight hint of fish oil, depending on how it's prepared. There's also something about its deep dark red wine color that feels luxurious.

It's easy to avoiding the fish oil taste of you're careful.

whales are definitely sentient, have language and culture - enjoy eating something else

I don't understand this "whales are definitely sentient" thing going around in this thread. How is this tested? What evidence do we have?
