I'm new to canning... last night I canned some tomatoes. I just diced them and raw packed them. I was pushing them down a little to make sure the jar was full and leaving 1/2" head space... but after processing, there is a lot of space in the top of the jar, at least full inch, and there is tomato sitting above the juices. These were roma tomatoes, not super juicy, and I didn't add any additional water or anything, just 1/2 tsp salt to each pint (I was following a very old copy of "Putting Food By"). The jars did seal, but I'm wondering if these are safe to store?
