My family is gluten intolerant and we use this product extensively.  Pancakes, biscuits, waffles, it doesn't really matter what you need to bake, this mix comes through.  This is my go to mix above Bob's and all others we have tried.  Try a box, follow the instructions for pancakes, and tell me they aren't awesome... go ahead... I dare you.
