Yes, you can leave that little twist tie on the bag. It won’t hurt the cranberries, but if you want maximum freshness, try to squeeze out as much air as possible before sealing the bag again.
If the bag is unopened and still factory-sealed, you’re golden. Just pop it in the freezer and forget about it until cranberry season rolls around again.
One friendly warning: don’t store the bag near the freezer door where it gets jostled and warmed up every time you grab ice cream. Aim for the back where the temperature stays steady.
When NOT to Freeze in the Bag
The only time I’d say skip the original bag is if it’s torn or already leaking juice. Then you’ll want to transfer them to something airtight, because cranberry juice in your ice cube trays is not a fun surprise.
Also, if your bag is one of those “breathable” mesh types, definitely switch to a freezer bag. Mesh allows moisture to escape, and that can lead to freezer-burned berries in just a few weeks.
But for 90% of home cooks, the original plastic bag works like a charm. It’s one of those rare moments where lazy wins, and you can feel good about it.
