My friend and I made jam for the first time yesterday. We were reading some posts and decided to sterilize/seal the jars by putting them in a 200 degree oven. We filled them up and they all sealed nicely. My friend is now freaked out that we might get sick. To be cautious we both put our jams in the fridge today. Do we have anything to worry about? Will the jam be a-ok if we keep it in the fridge? Thanks!
