No, I actually didn't bake it in the jar; the jars aren't recommended for baking. I put in a crust, then the cooked filling, then another crust, and shut the lid. I imagine in hot, humid weather it might become moldy fairly quickly; but in winter, when I did it, it lasted a surprisingly long time. You could always refrigerate if you're worried about mold, then reheat just prior to serving. Good luck - PJH
