Is there a way to can fresh garden salsa without boiling it. I use Tomatoes, Cilantro, Garlic, Jalapeno, Lime Juice, Onion, and mayhap another pepper if I feel like it. We have tried to do the boiling canning method, but it took away the crunch of the fresh veggies and did not taste the same. I was thinking of some way to just suck the air out. Even if it required refrigeration. Possible?
