This looks great. Have you experimented with flavors etc? I want to make my own hazelnut chocolate bar, could I finely chop hazelnuts and add them to the mixture then pour into the mold's? Also what about storage I work 12hour shifts and would like to take some with me to work how should I store them? Wrap it in foil perhaps? Or is there some kind of chocolate bar storer on Amazon or something like this?

Thank you!
