Wash the meat and fins well. The fins will have some natural slime on them, so clean them off to remove excess fishy flavor. Pat dry when done.
Sprinkle cayenne pepper, salt and pepper on each side of each piece of meat.
Set your grill to medium-high heat. Brush each piece of meat with melted butter before placing them on the grill.
Grill each side for about three minutes, or until the meat turns opaque and starts to flake. Brush the meat with melted butter after the first flip.
Serve them while hot with a lemon garlic butter. To eat, hold each fin like it’s a toothpick and gently bite down in front of each fin. The meat is completely boneless, besides small blades of cartilage that are attached to the fins. When cooked correctly, the meat will slide right off of the fins and cartilage.
