After the fish has been cleaned, lay the salmon on a clean
dry cutting board. I prefer using two knives for filleting
salmon. I use a 10 inch butcher knife to cut through the
bones and a fillet knife to remove the ribs. It is also
handy to have a towel nearby to wipe your hand and/or to
hold the salmon during some portions of the cutting process.
The towel will absorb the fish slime and will give you
something to hold the fish firmly with.
Start by laying the fish with it's back toward you near the
edge of the cutting board. Start just behind the head and
begin to cut toward the tail with the knife blade in contact
with the vertebral column and at a slight incline to cut as
much meat as possible along the back. You will be cutting
through the ribs as you perform this process. Continue
cutting until you reach the tail end. Place the newly cut
fillet aside.
After completing the cutting on one side, flip the fish over
and now begin at the tail and perform the same process by
cutting from the tail toward the head. As you approach the
dorsal fin, take special care to cut around it and then
continue cutting until you've reached the head.
You should now have two fillets. Go ahead and discard the
salmon carcass, or use it for crab bait or fish stock.
The next task is to remove the rib bones. Start by slipping
the fillet knife gently between the rib bones and the flesh.
You'll want to keep the fillet knife as close to the ribs as
possible, making sure not to cut too deeply or you'll be
removing more flesh than necessary. Once the ribs have been
removed, trim the fillet to remove any fat around the belly
area and/or around where the fins once were.
The last step of the process is to remove the set of bones
that were cut through during the filleting process. I prefer
to use a small pair of needle nose pliers to pull the bones
out of the flesh. By running your thumb down the line of
bone ends, you can gently lift up the bone end and grab it
with the pair of pliers. Continue until all of the bones
have been removed. The fillet is now ready to be used in
your favorite salmon recipe.
