It came out really good last week, and we didn't finish all 6 rolls that I made, so I froze them and thawed them for this week. Yeah! 1 less thing to cook on a busy Friday!

I now keep a baking mix made up in a resealable container. I mix 1 cup white rice flour, 1/4 cup cornstarch, 1 tsp salt, and 1 tsp xanthan gum. I usually make 2 cups worth at a time, and when it gets low I add more to the same container. I use this mixture for all my baking, including the challah. I'm back to my old techniques, which means not really measuring how much flour I use.
So it's 1 packet yeast, 1 cup warm water, 1/2 egg (the other half for coating the top before baking) 1 tablespoon oil (or a glug of oil

) 1 tablespoon sugar or honey. I mix the water, yeast, and sweetener, let it bubble, then add the oil and egg, mix together, then add the flour mixture until the texture seems right. It's probably somewhere around 2 cups flour total, maybe a bit more. Then I let this rise a while, then make into little balls and fill the muffin tin with balls of dough, carefully coat with reserved egg mixture and sprinkle sesame or poppy seeds on the top, bake at 350 until it looks and smells done (maybe half an hour?)
This recipe makes 5-6 rolls which is plenty for us, since I'm on a low carb diet and nobody else seems to want the gluten-free challah.
