I have used non-sourdough wild-leavened bread recipes in the past, and found them to give me inconsistent results. They often amount to creating a new sourdough starter at the same time as making the bread, which is a bit of a gamble, and can leave you with barely-leavened bricks for bread. Usually, I'd much rather have enough time to build up a powerful starter before trying to make bread out of it. So I would have foolishly ignored this recipe, except for knowing that dosas and idli do work.
Buckwheat BreadSoak five cups of whole, raw buckwheat groats in a large bowl of spring or filtered water for 8-12 hours. Rinse and drain the buckwheat groats (the water becomes quite thick).
Add 2 teaspoons of salt and 2 cups of water. Puree with an immersion blender until a smooth batter forms. You can also mash them (minus the water) in a large mortar and pestle. Cover the bowl with a tea towel and let the batter ferment until it's bubbly and swollen--it may reach 1.25-1.5 times its starting volume, but after that it won't improve. In the summer, this takes another 12 hours or so, but in the winter, it may be more than 24 hours. If it doesn't look risen at all, give it a stir every 12 hours to keep the surface from getting funky.
Very gently, give the finished batter a brief stirring. It will have some larger, loose bubbles, as well as very fine bubbles like beaten egg white. Scoop the batter into two well-buttered bread pans and bake at 400 degrees for 15 minutes (no need to rise in the pan). Turn the oven down and bake for 45 minutes more at 350. Let cool for 10 minutes or so before gently removing from pans. Cool on a rack, covered with a tea towel.
This bread is at its most convincing when fresh from the oven. It doesn't age very well. I keep one loaf out at room temperature, covered with a tea towel, and it doesn't dry out to too much in the few days it takes me to finish it. The second loaf I store in a plastic bag in the fridge and only eat toasted. Once it's stored in plastic, the crust softens in an unappealing way and is prone to mold growth.
