What causes weeping jelly?
Weeping jelly (syneresis) may be caused by too much acid, a storage place that was too warm, a storage temperature that fluctuated, or layer of paraffin that was too thick.
Note: Sweet spreads should not be sealed with
paraffin because of the potential for mold growth. Seal
them with two-piece, self-sealing lids and process for 5
minutes in a boiling-water canner below 1,000 feet and
ten minutes if you live above 1,000 feet.
