So I went with this recipe and believe I got great results.
Steelhead filets skin to skin in canning salt in fridge for 3-weeks.
remove, good rinse and cut into bite size portions. 3/4x3/4 plus or minus
At this point, I wish looking back that I would of skinned them. I ended up doing it latter and I believe it was more work.
Mix a pickling solution of two parts apple cider vinegar to one part sugar. For this recipe I used three cups of vinegar to one and a half cups sugar. Slowly dissolve the sugar completely in the vinegar
boil, Add pickling spices, pepper corn.
While that cools cut up some Walla Walla onions. They are great pickled. Add lots!
mix fish and onion and brine in a non metal container with lid. Refridge for 3 weeks. I snuck a few pieces early and they get better with age.
remove and put into containers and keep refrigerated. I have shared with friends that don't like pickled anything and they went nuts. good luck, Hawgdawg
