As I mentioned in a different thread, my wife was diagnosed with Celiac a few weeks ago. She is going on about two and a half weeks gluten-free. With this last weekend being Easter she wanted some of her traditional things to eat, so we set out attempting to make them gluten-free. To my surprise, we had great success!
My wife comes from a Polish family so one of their Easter traditions is pierogi. She made these with her mom, so I don't know exactly how they did it, but again it was the same mixture of the above ingredients including xanthum gum, in slightly different proportions for the dough. Those also turned out fine, could not even tell the difference between the regular kind and hers.
Finally she wanted to make a coffee cake for easter brunch. We used the Bob's Red Mill muffin and baking mix, and then basically made the recipe that is on the Jiffy box. We found that we needed to add quite a bit of extra milk (appx 3/4 C - 1C), but once we did that, it was fine. We served it to her unsuspecting family and they didn't know we had done anything different.
I was glad to find out that it can be done!
