It sounds weird but I can assure you it’s not. The salmon collar holds so much flavour, and also has a bone right in the middle, so it guarantees you a more rich piece of fish, but also lends itself very well in a fish curry. You can get fish collars fresh from your local grocer or frozen as well. They are very inexpensive, but taste like a million bucks. The collar is usually a wasted part of the fish for a lot of people. It isn’t as pretty and has a large bone through the middle, so people tend to pass up on it. That’s why it’s cheaper than a filet of fish.
