On Friday some friends and I got together and canned six batches of salsa. The next morning I realized that we had left the lemon juice out of one batch, because I had some juice left over and shouldn't have becaues I had gotten just enough for 6 batches. The batches are all mixed up so I have no idea which jars are missing the lemon juice. We cold packed the jars and water bath canned them for 30 minutes. Will the salsa be safe to eat? I am concerend because I have heard that if you don't add lemon juice for acidity, you can get botchulism. Help! I don't know what to do!
