I'd imagine they'd be fine. If you refrigerate them first, then I woudn't set them directly on top of the dry ice, put a towel or several layers of newspaper, or cardboard in between. No point in freezing them and loosing any more quality in texture or consistency.
Maybe it's just me but if you're in the northern part of the states, with temperatures being fairly cool, 8 hours isn't that long. You're not talking about driving from Florida to California in August so you should be just fine. |
