Canned trout! Chunk the trout put in a pint quart jar, add one tablespoon of salt, one tablespoon of vinegar and one of olive oil a dash of liquid smoke. Put jars in the canner at 10lbs pressure for 90 minutes and presto you have a canned trout. Great for snacks or use as you would tuna. You need to have quite a few trout to do a canner load, but if you do it's a nice way to utilize them.
If you only have a few of them I enjoy them best fried for breakfast with bacon and pan fried potatoes, especially while camping.
