Firstly, mill the flour.
Then, add salt and baking soda to the flour, stir to combine.
Pour the buttermilk into the flour mixture, and stir until there is no more dry flour left.
Cover and then let the mixture sit at room temperature for 15-20 minutes. This will allow time for the freshly milled flour to absorb the liquids, and for the bran to start to soften.
Prepare a baking sheet with parchment paper, or grease well.
During the end of the rest period, preheat oven to 400*F.
After the rest period, then transfer the dough onto a lightly floured work surface. Knead dough by hand for 5-10 minutes until dough comes together.
Form the dough into a 8 inch round ball, then slightly flatten with hands.
Place the bread dough ball onto the prepared baking sheet. Then, with a sharp knife, score a "+" (plus sign or cross) into the top of the dough. Make sure the cuts go at least ½ inch deep.
Bake bread for 45-55 minutes or until the internal temperature of the center of the loaf reaches 195*F. The top should be golden browned, and the bottom should sound hollow when you tap it. (Be careful, it is hot)
Let rest for 10 minutes, then slice and serve warm for best results.
