I canned some jelly today. The recipe called for 6 cups of sugar and 2 packets of liquid pectin (6 oz). The only liquid that is called for is cider vinegar (2 cups). I processed them for 15 minutes. I have used this recipe before and it has come out beautifully. However, this time, a few of the jars have some liquid on the top. The jars are nearly cool and the jam is set, but there is about a teaspoon of liquid on the top. What do you suppose this could be and do you think it is safe to eat? I am worried that maybe some water got into the jars when I was putting the lids on before I processed them-- I keep the lids and rings in water to sterilize and perhaps some water dropped into the jar as I was screwing the lids on? So, presuming it is water, is it safe to consume? I'm going to put them in the fridge for now just to make sure.
