* I like Guittard, Valhrona, El Rey or Callebaut. The important thing is to use the best quality you can afford and don’t use chocolate chips.
** This is my personal bias but I feel it’s important. Unless corn syrup is labeled “organic” it is made with genetically modified corn. As there are no tests showing that gmo’s are safe, and because there are studies that indicate that they may be harmful to our health, I strongly suggest taking the time to find organic corn syrup. I suspect that you can substitute agave syrup but I don’t know how it may alter the finished fudge as I haven’t yet tried making the fudge with agave syrup.
