The verdict: I am not in love with the strong taste of the quinoa flour; but blending a couple of different types of grains is probably the best way to go. So, if you do want to try making these muffins, maybe do a 50/50 mixture with another grain.

Don't worry, I have no plans of completely abandoning you Udi, I am happy to support a local business (Udi's Bakery is located in Denver) and will grow increasing lazy about baking as my belly expands over these last 10+ weeks. But for today, I give myself an "A" for effort!
On a more serious note about Celiac disease, it can be extremely debiliating to a person who has it, but doesn't know it. It is very hard on the body and makes them feel miserable each time they eat, which is a lot of a person's life.
