"Never fry super-delicate fish, as they fall apart," recommends Chef Becker. This means you should steer clear of frying fish like tilapia, branzino, sole, and flounder. When flipping them over, these fragile fish can easily break apart and overcook faster than you think. You'll either end up with breading that isn't crisp enough or an overly dry interior. Either way, it won't be an enjoyable meal.
