Fish always freaks me out, because I don't know how to handle it. Take oil sardines with the starry eyes. Am I supposed to eat the sardine whole, with head, eyes and tailfin? Am I supposed to bite the head off and spit it out? Cut it off? It's so basic and I feel like an idiot, but I really have no idea.
Eating fish takes a lot of skill and practice but the basic procedure is to remove the skin from the grilled fish with ultra care using a fork and knife. This will be very hard at first. It’s a skill.
Then remove whatever is left of the lungs.
You are left with the head, the white meat around the fish bone and the fin.
You will now just pick on the meat and eat it.
In the end you are left with a head, a fish bone and a fin. These 3 should still be connected and intact.
Sardines are the hardest because you will have to do it for 6 to 10 sardines (6 is the minimum acceptable portion).
Start with a big fish like a sea bass or something similar.
Good luck
