I love white chocolate but have always found it to be much too sweet. Some weeks ago I ordered the Sweet William brand from Viva Granola.
It is amazing, really not sweet and "smooth" as they write on the package. They are an Australian company that make various chocolate products; blocks, candy bars, baking chocolate etc. They even have a No Nut-"nut" bar, the roasted soy beans make it nutty.
Sadly, Viva Granola does not have any right now and going to Australia to get some more is not in the budget right now.
