Yes these are cooked on my egg. It’s important to not allow the coals to flare up or the scales get charred and they’re nasty. Not hard to do but I overlooked that once. They will not stick to the grill with the scales on. Easy to cook, easy to serve and easy to eat. The last ones I did I put a dollop of real butter on each fillet along with some fresh minced garlic. They were incredible.
