Mill grain on fine setting (Mockmill - set to '0,' Wondermill - set to 'Bread,' Nutrimill - adjust to 12:00 position). I like to use 70% hard white wheat, 15% khorasan and 15% soft white wheat.You can also make this recipe with store-bought whole wheat flour. This step is called making the sponge. In the bowl of a stand mixer, combine warm milk (about 100-110℉), lemon juice, and half of the fresh flour. Stir until combined and then cover and let soak for 15 minutes.
Add the remaining flour, butter, honey, egg and instant yeast. Knead for 5 minutes and then add the salt. Mix together all of the dough ingredients, to make a smooth, supple, and slightly sticky dough that passes the windowpane test. It will take about 15-20 minutes with a KitchenAid mixer, 8-10 minutes with an Ankarsrum mixer, 22 minutes with a bread machine, or 30+ minutes if kneading by hand.
Turn the dough onto the counter (use olive oil instead of flour to keep the dough from sticking) and shape it into a ball. Place the kneaded dough in a lightly greased bowl, cover the bowl, and let it rise for 50-75 minutes, until doubled in size.
Once the dough has doubled, it is ready to be shaped! Lightly grease the counter (and your hands!) with olive oil and turn the dough onto the prepared surface. Divide the dough into two equal pieces. Shape each half into a rectangle that is a few inches shorter than your bread pan. Roll it up tightly, pressing lightly to seal as you go. Tuck the ends under and place it seam-side down in your greased bread pan.
Preheat the oven to 375°F. Cover loosely with a tea towel and let the shaped loaf rise until doubled in size. To test if the dough has risen enough, gently press your thumb into the corner. If the indentation slowly springs back, it's ready to bake. If it fills in immediately, it needs more time; if it stays down without moving, it's likely over-proofed.
Bake the bread at 350℉ for 25-35 minutes, until the crust is golden brown and the sides of the loaf feel firm. The internal temperature of the loaf should be about 195°F. Remove the loaf from the oven, and turn it out of the pan onto a rack to cool. Let it cool completely before slicing.
