So I made a gluten free loaf with a starter I made based on your guide. I have a raisin and honey starter, and I pulled it out of the fridge and fed it after I woke up. Before I went to bed I mixed 1 cup starter with 1 cup homemade gluten free flour mix, small bit of grapeseed oil, and about a teaspoon of salt. The next morning I mixed the starter mix with one cup GF flour mix. I covered the bowl with a damp towel and put it on top of the fridge for a couple of flours. I heated up a dutch oven in a 450ºF oven for about an hour. I gently grabbed the dough, floured the bottom and put it in the dutch oven for 30 minutes. I then removed the lid and cooked it for about 20 more minutes. It turned out great! It was very much like store bought white bread. The dough was even making kind of fizzing noises before I put it in the oven! It also toasted beautifully! I'm going to do some more experiments, but so far, so good!
