When poured into a larger mold and cut into pieces, the jelly tends to release some liquid after a few hours of cutting. This is normal and does not mean that the jelly has turned bad. You can still consume the jelly and it is still as good as new. One way to prevent the jelly from melting is to cut it only before serving. Another way is to pour it into individual serving cups. That way, the jelly will remain solid for a good one week.
