Gluten-Free Sourdough Starter

Step 1
Mix together the brown rice flour and the buckwheat flour until well combined.

Step 2
Day 1: Whisk together 1 cup of the flour mix and 3/4 cup filtered water in a glass jar. Stir well until smooth and no lumps remain. Cover with a piece of cheesecloth or a clean linen towel and let sit at room temperature (about 70 degrees F (21 degrees C)), far from drafts or direct sunlight. Do not cover with plastic wrap, the circulation of air is important. Every once in a while, stir the mixture with a fork or whisk. Check to see if small bubbles start to form in the mixture. These bubbles indicate that wild yeast is forming.

Step 3
Day 2: As well as stirring, you will begin to feed the starter on day 2. In the morning, mix 1/4 cup of flour mixture and 3 tablespoons room-temperature filtered water. Once mixed well, add the flour-water mixture to the jar with the starter mixture. Stir well and continue to stir throughout the day if possible. Every 12 hours, add this same feeding mixture (1/4 cup flour plus 3 tablespoons water) to the mother mixture.

Step 4
Day 3: By now, you should notice an overall sponge-like texture. If this is the case, your starter is ready to use. At this point, it should be kept in certain conditions to keep from over-growing. Keep it sealed, in the refrigerator.

Step 5
If your starter has only a bit of foam at the top, but you notice a fragrant smell of yeast, these are good signs and could be that the room is too cool. Check to make sure the location is draft free. If you don't notice these minimal signs and a note a foul smell, discard starter and restart.

Step 6
If your sponge is still very watery but has a sponge forming, mix well, take out 1 cup of the mixture, and discard (or use in another recipe) and feed the starter every 6 hours.

Step 7
By day 4 your starter should be ready. Keep the starter covered in the refrigerator and feed very two weeks or each time you measure out any starter.
