Place the mixing bowl on a kitchen scale that is set to grams, then hit the tare button. The tare function tells the scale not to count the weight of the bowl, which is important!
Add the hungry or active starter, bread flour, diastatic malt powder (if you are using it), whole milk, yeast, sugar and salt to the mixing bowl. I use the tare button between each addition to measure directly into the bowl.
Knead the dough in the bowl of your stand mixer with the dough hook attachment for about five minutes, or until the stiff dough clings to the sides and feels soft and only slightly sticky to the touch.If the dough is too dry, add a splash of milk. If the dough is sticking to the bowl and seems too wet, add flour gradually until the texture improves. There is a bit of intuition involved with making sourdough recipes, but you will get the hang of it! Leave the dough in the mixing bowl, cover it with a tea towel or plastic wrap and place it somewhere warm to bulk rise for an hour for the first rise. I turn my oven on to preheat for a few minutes, then shut it off to create a proofing box of sorts or boil a cup of water in the microwave and then store it in my modified proofing box.
After the dough has warmly rested for an hour, it will feel soft and pillowy. At this point the dough can be long fermented overnight or up to 4 days in the refrigerator or baked immediately.On a clean work surface remove it from the mixing bowl and divide the dough into eight equal pieces using either a knife for pastry scraper. Form each piece of dough into smooth balls and then gently roll them into a long rope. Shape the dough by twisting the middle together and bringing the ends down to form a pretzel shape.
Let the pretzel dough rest on the counter for the second rise for about 30 minutes, covered by a tea towel. Bring a large pot of water comes to a boil and preheat oven to 350°F.
Once the water reaches a boil, add 1 tablespoon of baking soda. The baking soda creates an alkaline solution that acts as both a binder and pH stabilizer to keep the pretzel shape during the boiling process.
Once the boiling baking soda bath is ready, add 2-4 pretzels to the pot. The shaped pretzels SHOULD NOT TOUCH EACH OTHER in the boiling water. Set a timer for one minute and let the bagel boil.
After one minute, flip the pretzels over with a slotted spoon and boil the other side for one minute more. Remove the pretzels from the water and let any excess water drip off before setting them on a parchment-lined baking sheet.
Brush the pretzel tops with an egg wash* and sprinkle with a pinch of flaked sea salt or seasonings. I'm using Everything But the Bagel Jalapeño and plain poppy seeds.
Bake the pretzels at 350°F for about 20-25 minutes. This could vary depending on your oven. In my oven, I place my sheet pan on the bottom rack and bake for exactly 25 minutes. Sometimes I rotate the pan after 15 minutes if they appear to be browning unevenly.
Once the pretzels are golden brown and cooked through (check for an internal temperature between 195-205°F), let them cool on a wire rack.
