Canning hot banana peppers

I did not get the recipe and wish I had. Years ago, my grandmother had a neighbor that took hot banana peppers, seeded them and fried them in just a tad in oil then canned them with vinegar some how. Anyone heard of this? I've tried my own version, but did not have good luck. ANY THOUGHTS? Would love to have a recipe for this. The taste was very unique and delicious.
