Cooking fish skin up has its advantages, one of which is that it helps to lock in the juices and flavors of the fish. Plus, who doesn't love a good crunch with their meal? It's like a little party in your mouth, with the crispy skin and the tender fish.
On the other hand, cooking fish skin down can result in a soggy mess, which is definitely not what you want. I mean, who likes a limp piece of fish, right? It's all about the presentation and the experience of eating, and cooking fish skin up just makes it more enjoyable.
Now, I know what you're thinking: what about the exceptions to the rule? What about the times when cooking fish skin down is actually preferable? Well, my friend, that's a great question, and the answer is that it really depends on the type of fish you're using and the cooking method.
