I can’t remember where I first saw this, but ever since, it’s how I skin a salmon. It’s genius.
Cut between the skin and the flesh at one end just to start it off. Then put some salt on the skin so your fingers get a good purchase and don’t slide off. Hold the skin and pull it, the same way you would if you were using a knife, and it peels away. Boom, done! How’s that for a top trick?
