Some times ago, I posted about the kneading power of my Kitchen Aid Artisan mixer not living up to it's power and kind of non-functional "C" hook that it came with. Since then, I have been kneading the dough manually. Last year, while perusing one of the cookbook Culinaria France one of the picture caught my eyes. It's a French bread baker holding up a large piece of dough right out of Kitchen Aid Profession mixer - kneaded and formed into a perfect "window pane". That got me persistent to get the same result with my Artisan. And here are the photo journal of it. I hope you will get encouragement and have a great bread baking result.
Tip: Use paddle attachment for 15 minutes to mix the flour mixture with water. Water:Flour ratio per your recipe but the moisture content of every bag of flour varies with season the flour is manufactured and type of wheat, etc, so use some "common knowledge / grand-mother's tip / family secret" sense of "ear lobe" touch test. Then, switch to "C" hook and knead until the dough forms into a ball and separate itself from the side of the mixing bowl. Stop and pull out to test. Depending on the dough's flour and water ratio, it will take anywhere from 30 min to 45 min for the window pane to form. **Flour used: All Purpose Flour
