I always have a difficult time eating anything where I have seen its eyes, including fish.
Just think of Atlantic and Caribbean lionfish as robotic egg laying killing machines designed to kill all the other fish. They’re basically like the Terminator crossbred with rabbits. In the pacific they’re kept in check by other species that know how eat them. In the Caribbean about the only thing that might eat them is the grouper, which has been nearly hunted to death because they’re really slow moving and easy to spear.
How long does it take to cook the venom out, does she have recommendations?
None. The venom exists in the spines of Lionfish not in the main flesh of the fish.
