How long can I store THAWED puff pastry in my fridge?

The plan was to make my very first cheese danish this weekend, so I thawed a box of frozen puff pastry sheets. Something came up and I was unable to go through with the recipe, and now the pastry has been sitting, thawed, in my fridge for a couple days now. Can I still use it? And if not, why not?

  1. If it's still in the plastic wrap that it was packaged in it might last about a week in the refrigerator. But unless it's kept hermetically sealed it will dry out, even with plastic around it.
    Ooops, perhaps I should explain that.
    Some plastic wrap is just pourous enough to allow for air/water vapor to invade/escape from adjacent environments. Moisture in the environment wants to equalize itself so food wrapped in inferior grades of plastic can lose moisture in the refrigerator/freezer. Wrap a piece of meat tightly (as air tight as posible) in a cheap plastic bag and put it in the freezer. If it develops ice crystals on it's surface, that's freezer burn, because it's leaking air/moisture through its pores.

      Hm, thank you. Yes, it's still unopened in the plastic. This is the first time I've ever used puff pastry so I wasn't sure how long it would keep.

    2. I have found that puff pastry that has been opened develops mold very quickly (about 5 days), but don't know about unopened.

      1. Hmmmm. I probably threw away some expensive stuff too quickly.

        The box said keep unthawed for one day only.

        (Probably should have checked or tried it. Was going to make some little cinnamon sugar things with the leftovers from my tart.)

        Live and learn.

          I would not keep it for more than 2 days as it is bad long before you see the mold.

          1. re: souschef

            Didn't you just say 5 days?
            What goes "bad" before it molds?

          2. re: karykat

            "unthawed?"

          3. Used to keep big sheets in the fridge for a few days at work. Never a problem. You can tell when there's mold. It starts with tiny black specks.

            1. Jessica please I need your advise the pack says
              expiration date Aprl 2013 - but it has been frozen all this time . Can I still use the shells>>

                Is the puff pastry still frozen? If it is frozen, never opened, and still in original sealed package it should totally be fine! Thaw and do the sniff test before baking but there is no reason they would have gone bad....even if the exporation date was listed as april 2012.

                1. re: rociopowers

                  the expiration date is only an indicator of best quality... I'd bake one and taste it :)

                  1. re: KarenDW

                    I was going to say this - the best before date is only an indicator of food quality and not food safety. Assuming it has been in a functioning freezer and is still sealed, it would likely be good for a week or so. As well, you will be cooking thoroughly, so that would kill any bacteria that may be there.
