I also cannot fince maple sugar locally. I asked in our local natural foods store and she didn't know what I was talking about. We did find date sugar though. Is this similar? I am also finding many choices of organic sugar.
I had the same problem but I asked the guy at Whole Foods and he said that Maple Sugar is a seasonal thing. He said that they will be getting it closer to Thanksgiving (so in maybe two weeks). They do have a vegan cane sugar at Whole Foods but I remember something about Alicia advising against it. However if it turned out well than you have some wonderful pumpkin bread until you can what you need!
