Poor Man's Steak in a Jar

Steps

1. Finely dice the onions and mix into the ground beef by hand until uniform and paste-like.
2. Coat the inside of a canning jar lid with olive oil and press the meat in to shape flat patties about half an inch thick.
3. Shape all the patties (about 8 to 9 from this amount of meat).
4. Simmer chicken bones in water with a teaspoon of salt and chopped onion for 1 hour to make broth.
5. Fry the patties in olive oil for about 10 minutes per side until a golden crust forms.
6. Stack the patties snugly in a quart-sized mason jar.
7. Wipe the jar rim with a cloth soaked in vinegar.
8. Add 1 teaspoon of vinegar per jar to lower the pH.
9. Close the lid but not all the way so air can escape.
10. Water-bath process for 3 hours at boiling (212F).
11. Let the jars cool so the vacuum forms on its own.
