Was wondering I did 10 quarts of tomatoes today. Only we were so in a hurry we forgot the salt. I read online it doesnt matter if you add salt or not. This was a absolute mistake we didnt figure it out till half way through the sealing process. I know stupid me. Anyone else have issues like this? I was too in a hurry. I know some people like salt but is it really needed? How long will my tomatoes last?
