As with all sourdough recipes, feed the sourdough starter and place it in a warm place several hours before you are ready to bake.
In the bowl of a stand mixer fitted with the dough hook attachment, mix together all of the dough ingredients. This will make a smooth, supple, and not overly sticky dough ball. See note 1 for same-day baking instructions.Start with a low speed, then gradually increase to a kneading speed for 8-10 minutes.The garlic knot dough should cling to the hook and be free from sticking to the sides of the bowl. 300 grams sourdough starter, 630 grams all-purpose flour, 42 grams powdered milk, 50 grams honey, 15 grams salt, 340 grams water, 57 grams butter
Place the kneaded dough in an airtight container with lid or cover with plastic wrap. Bulk ferment for 4-6 hours at room temperature.
Once bulk fermentation is over, grease a pan. See note 2 below for sizes.
Roll the dough pieces into 12" long rope and tie in a knot (it's like tying shoes, but without the bow). Arrange the shaped knots in the prepared pan.
Cover the unbaked knots with aluminum foil, plastic wrap and put the rolls in the refrigerator overnight to bulk rise for 8-12 hours or even longer!
The next day, take the rolls out the the refrigerator 2 ½ hours before serving. Place the rolls in a warm spot to let the dough rest and preheat the oven to 375℉ degrees Fahrenheit. For best results, move the rack to a low position so that the rolls can be baked to golden brown.
Bake at 375℉ for 45-50 minutes. Check the garlic knots after 20 minutes, and if they are over browning, cover with foil. The garlic knots are done when the center temperature of the rolls reach 195℉.
In a microwave safe bowl, melt together the butter and garlic powder. Brush the fresh baked rolls with garlic butter mixture while still warm. Grate parmesan cheese over the tops and sprinkle with fresh parsley.
