Ex Input:
Makes pretty good cocoa and a lot easier than on the stovetop.  Not as sweet as I would prefer and needs to be stirred to keep it in suspension.  I guess I can add marshmallows:-)

I tried this gum after Trident cinnamon became hard to find a couple of years ago.  (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.)  I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back.  It does last a long, long, long, time.  Unfortunatley, as other reviewers noted, it has become very hard to find in stores.  Trident cinnamon is everywhere but now I don't want it.  Amazon saves the day again.

I have always trusted the Bisquick name, so I decided to buy this product.  I was thrilled with the pancakes and muffins I was able to make.  The only thing I have a problem with is the size of the box.  It's very small.  Like most GF product, you pay much more than you would for the non-GF counterpart. :(
