Well here is the recipe for pickled fish here is what you need. Approx 6 pounds of fish fillets cut up into bite size fillets. There is usually roughly 1 pound of fish per jar depending on how big your jars are.
You will need to cure your fish for about a week. To do this put your meat in a container along with 2/3 cup salt and pour enough white vinegar into the container to cover the fish. Mix this up good and let sit for 5 to 7 days. The fish will still have the Y bones in it, the salt and vinegar will eat them away.
I usually let mine sit for 7 days and make sure your stir them daily. I usually use a big tupperware container that way you can just tip the container over to stir it rather than opening it up and stiring it with a spoon. Something with a sealed lid is best so it doesn't smell up the fridge.
After the week is up you will rinse the meat off real well with cold water and pack it into jars alternating between meat and onion. Put as much or as little onion as you like. I love a lot it adds to the flavor.
In a pot on the stove add
2.5 cups sugar
2.5 cups white vinegar
2.5 cups white wine (I use a boones farm white wine I can't think of what its called but its the only white wine they make it just comes in a jar.)
2 tablespoons picklings spices (This is just a spice jar you buy at the grocery store that is called pickling spice and I put the spice in a cheese cloth. Just cut a big square of cheese cloth and put the spices in the middle and tie it shut with a twist tie that way you don't have all that stuff floating in your jars)
Boil this for 5 minutes and set aside and let cool.
Once this is cool pour it into the jars of fish. I usually let the fish sit in the jars for at least 4 days but the longer it sits the better it tastes. If you have any questions let me know.
