Measure the three ingredients in the yeast mix into a bowl. Whisk to combine. Set aside
Measure the binding ingredients in a separate bowl. Whisk to combine. Set aside
Measure out the dry ingredients in a separate bowl.
Add dry ingredients into your stand mixer. Give them a quick stir to combine.
Add the yeast mix and the binding mix to the dry ingredients in the mixer. Start kneading. The mix will be very dry at first.
When the mix starts to combine, add the apple cider vinegar directly to the mixer.
Knead until the dough is combined, passes through the dry stage and starts to stick to the side and bottom of the mixer.
Place the dough on a surface lightly coated in sorghum flour. Divide into two equal portions. Shape each portion into a flat rectangle, roll into a log, secure the sides and seam at the bottom. Set loaf on a piece of parchment paper on a cookie sheet or loaf pan. Repeat with other loaf. Make sure the parchment is between the two loaves so they don't join together in the oven.
Cover and let rise 45-60 minutes. About 30 minutes into the rise, set the oven to 450 degrees and add a metal pan on the bottom rack of the oven.
After rising, score the bread four or five times. Place the bread in the oven. Add about a half inch of water to the metal pan at the bottom of the oven. Close the oven door and don't open for the first 10 minutes of the bake.
Bake for 40 minutes. Rotate half-way through if needed.
Let cool on a cooling rack before cutting bread if possible. If not possible, let it sit at least 15 minutes before cutting.
