A fresh black truffle tuber brumale is a sort of chocolate confection that's made with a dense, rich chocolate middle that can be flavored with extracts (or on this case, wine), and then coated in either stable chocolate, Bagnoli's Black Truffle cocoa powder, nuts, or other substances. I recommend storing them in a plastic freezer bag inside another covered container to protect the chocolate from freezer burn as finest you may. If freezing, I recommend storing them in a plastic freezer bag inside one other covered container to guard the chocolate from freezer burn as Finest Truffle Products you possibly can. TO FREEZE: Homemade chocolate truffles could also be saved within the freezer for up to six months. Bars could also be stored in an airtight container in the refrigerator for up to 1 week or within the freeze, wrapped in parchment and foil and positioned in a zipper bag for up to three months. Place the bowl within the refrigerator to firm up for 1 hour.
