There is a post somewhere here on the forum where a woman was asking for a gluten free sourdough recipe. Well I was online tonight looking for info on Sourdough and came across one. Here it is for you and I will post the website as well. I just hope the person who was looking for a recipe sees this post.
Sourdough Starter, Gluten-Free
-large glass, plastic, or pottery container–like a bowl, a jar, or a measuring cup–be sure it can hold about 6 C of dough
-something porous to cover the container with like cheesecloth or parchment paper that is poked full of holes (don’t use aluminum foil)
-Sorghum Flour plus some others: any or all of: Brown Rice flour, Amaranth flour, Garbanzo Bean flour
-Water (we have filtered water in our house that contains no chorine–and I think that does the best)
-Organic red cabbage leaves (although I heard that people have had good results w/non-organic as well)
Place 1 C (5 oz) of sorghum flour and 1 C (8 oz/250 ml) of water in your container. Mix thoroughly (I’ve been using a whisk and it’s worked well). Add 1 or 2 leaves of red cabbage. Mix those around with the flour-water slurry.
Cover with your porous material. You can also leave it open if you don’t have fruit flies bopping around your kitchen like I do–leaving it open will encourage more wild yeast from your kitchen to land on the mixture. Leave it on your kitchen counter.
Stir it every so often–no stress, just when you think about it. About 12 hours later, add another 1 C each of sorghum flour and water. Mix well.
Repeat this process every 12-ish hours. After about 48 hours you should see some bubbling action in your starter. Once the bubbling action is definitely in place (wait another full day), then you can remove the cabbage leaves.
Congratulations! Your starter is on its way. Now you need to feed it every 12 hours or so. Play around with the flours you feed it with–I’ve been alternating sorghum, brown rice, amaranth, and garbanzo bean flours. You can see and smell how each of these affects your starter.
