Recipe Notes

The fudge can be stored in the freezer for longer term storage. 

*The granulated version of Pyure sweetener blend will work as well. This sweetener is twice as sweet as sugar. Substituting this sweetener with other brands may cause this recipe to not turn out--especially if extra bulk is needed to create the same sweetness level
