Heat a heavy frying pan till it's very hot - you'll know when it's hot enough if you flick some water from your fingers into the pan, and it doesn't just lie there sizzling, but runs about in the pan in tiny balls.
Put a couple of drops of oil in the pan, and spread it around with a paper towel to coat the surface thinly. (Salmon is an oily fish, and will cook in its own oil).
Place the fish in the pan. It might well stick to the pan at this point, so place each piece carefully!.
Keep cooking, and occasionally shaking the pan until the fish no longer sticks. Then turn the fish over and do the other side, again until the salmon unsticks by itself. (Don't be tempted to use a spatula to unstick the fish, or the fish will likely break up).
The end result is salmon that's crispy crunchy on the outside, and deliciously different. You could dab a piece of lemon or herb butter on top if you're so minded.
