Maple Cotton Candy!
Yes, cotton candy made from maple syrup sugar.
I read about it awhile ago. I can only get it at the Union Square Green Market. The company only makes small batches so it sells out pretty quickly (read that as, I have to get to the Farmer's Market relatively early when I want to buy some.)
The farmers that make it dry their maple syrup and grind it in to a fine sugar. They had to have a cotton candy machine specially made because the maple sugar has finer grains than regular cotton candy sugar.
It is the most delicious cotton candy, like little puffs of maple that just melt in your mouth.
