Is is possible to make these then freeze them? I'd like to make some to ship to friends, and I'm hoping freezing them will help them last longer....

I don't generally ship truffles, and when I do, it's 2nd day air. Depends upon how you finish your truffles. If you go traditional and roll them in cocoa, (ir even ground nuts, powdered sugar or coconut) you can refrigerate them just fine, because the appearance will not be affected. If you've dipped them in tempered chocolate, you may experience some bloom on the coating.

Hopefully someone with more chocolate expertise than me can weigh in, but I think refrigeration may have the same discoloration effect as freezing. It's about the change in temperature. Unfortunately, I'm not sure what the optimal way is to store them.

Thanks for your response, Monita. I think I'll just keep them in the fridge and hope for the best :)

You could freeze them but it may cause discoloration of the chocolate
