Flip the salmon over skin side up, firmly hold the sides of the filet and curl it upward by pressing the sides slightly in and carefully score the skin across by slicing your
knife through the skin about 1/2 an inch deep. (be sure to do this just across the top of the skin but do not slice all the way through the fish like you are going to cut it in half and try and keep the scores about 1/4 an inch apart, the closer the scores the crispier the skin)
