I see that my grocery store has just started stocking Betty Crocker's new line of gluten-free mixes. Has anyone tried them, yet? I have several colleagues who are gluten-intolerant, and when it is my turn to provide dessert for our weekly meetings, I don't want them to feel left out. However, no matter how hard I try, and what recipe I use, I've had zero success in baking gluten-free brownies. I'm curious to give the mix a try, but am concerned not only about the taste, but whether it is truly gluten-free (i.e. won't cause problems for my colleagues).
