I started to make my batter bun recipe (Look for my gluten free batter buns!)and I added some tapioca flour to see how it would work as well as Xanthum Gum, and when I opened my oven to take them out when they were done baking, like were like a popover, as they had popped up! They were delicious and they are very easy to make. I don't have a popover pan, so I was just using a muffin pan, and they turned out fine with it, but if you have a popover pan, you may probably be able to use it. These are also dairy free, as I used a gluten free, dairy free butter! Enjoy! **UPDATE** I have received a couple of e-mails telling me that spelt is a form of wheat and is not at all acceptable in a gluten free diet. I have a Bob's Red Mill baking cookbook that says that Spelt is a cousin of wheat and is found to be tolerated by some of those that are allergic to wheat. Trader Joe's has a spelt bread that the label says the same, that some celiacs have found to be able to eat Spelt flour. I am new at using a gluten free diet (It's for my daughter who is autistic, but not allergic to wheat), so I am sorry if this has confused anyone. You could try using a wheat/gluten free flour for the popovers and see if they still come out ok! Sorry about any confusion.
