If properly harvested, Thresher is amazing meat and the belly might be some of the best meat the ocean offers. I was speaking with Yanni about this subject years ago and he said its one of his favorites! Steaks are amazing, you can also cube and grill.
I served a part of 20-30 people with some of my thresher. I made sliders with Hawaiian sweet bread, a chipotle aioli and slaw. I informed everyone ahead of time that it was shark. People were amazed by the flavor and said it was some of the best seafood they had ever had!
Here is a little recap from my thresher catch in 2017.
Cheers,
