I'm getting the hang of it! This is my second round and we're now amassing a stock of tomato sauce to get us through the winter. Yahoo! It is time consuming and messy but rewarding. I followed most of the rules: sterilized the jars and lids, hot bath (low boil) 50 minutes, but I did forget to add lemon/lime juice and salt which I understand insures a good preserve. Fingers crossed!
