Can you eat jam with mold on it?

The mold itself should never be eaten, but it can be removed. To do this, simply carefully remove the top layer of mold with a spoon. If the remaining jam has a good taste and flavor, put it in the freezer to completely kill the bacteria, and after a while, you can safely eat it.
