I made a batch of cranberry salsa and when I ladled the hot preserves into the hot jars, I heard a cracking noise while filling the jars but processed the jars anyways in a hot-water bath. The jars in the oven at 375'F. Were the jars too hot? Was the salsa to hot? I usually use a water bath to sterilize the jars but have sterilized jars in the oven before.
Can I salvage the salsa? How? Reheat the salsa and use new jars?
