Add 930g of the flour to the bowl of the mixer, then add the liquid mixture to the flour. Reserve the remaining 70g flour. Attach the dough hook and lock the mixer head in the down position. Start the mixer on its lowest speed to combine the ingredients.
Once all the flour has been incorporated, increase the mixer speed to medium-low to knead and run it for about 7-8 minutes. If you see a lot of dough sticking to the sides, add in 1 tbsp of the reserved flour and let it become fully incorporated. You may need to do this 3 or 4 more times during this step.
After 8 minutes, stop the mixer and use a flexible dough scraper (silicone spatula is fine too) to scrape down the sides of the bowl. The dough should be tacky but not impossibly sticky at this point; if it is impossibly sticky (i.e., you can't rub your hands together and get the dough completely off your fingers), add another tbsp of the reserved flour to the bowl and knead another minute or two.
Test the dough strength with the windowpane test: tear off a chunk of dough approximately 2 tbsp in size. Hold the piece of dough up to a window or light, and, using your fingers, pinch and stretch the dough into as thin and flat a shape as you can. If you can stretch the dough so that light comes through the dough without the dough tearing, the dough is ready for its first rise. If the windowpane tears, return the dough to the ball and knead for another minute or two and test again. Note: the dough probably doesn't need any more flour at this point, just more kneading.
Depending on the size of your mixer, you may find as the dough nears completion, it may start creeping over the top of the dough hook. If that's the case, it's best to pull it out of the mixer and complete by hand. Use the dough scraper to release the dough from the bowl and hook and transfer to countertop to knead by hand. The dough may seem very sticky coming out of the bowl, but use the dough scraper to release the dough from the countertop, adding a little flour only when absolutely necessary. As you knead by hand, some dough may stick to the countertop as you pick up the dough and rotate it. If it's a very small amount of dough, scrape it up with the dough scraper and continue kneading. If a lot of dough is staying on the countertop, add 1 tbsp of the reserved flour and knead it in. The dough will become less sticky as it gains strength.
Once the dough passes the windowpane test and is not overly sticky, skip to "Rising the dough" below.
