What the freezer time means
Freezer times from USDA FoodKeeper are about quality, not safety. Food kept frozen at 0 F (-18 C) stays safe indefinitely; what changes over the months is texture, moisture and flavour. Wrap puff pastry tightly, press out air, and label the pack with the date so the window above is easy to track.
Thaw in the fridge, not on the counter. Anything that thawed in the fridge can be refrozen, with some further loss of quality; anything left at room temperature for more than 2 hours should not go back in.
Storage habits that make the difference
Keep refrigerated dough cold at all times and return it to the fridge promptly after use, since raw dough with eggs or dairy is not safe left at room temperature. Freeze unused portions in a sealed bag or container, and thaw in the fridge rather than on the counter before baking.
