Pre-heat the oven to 450°.
In a standing mixer bowl, add in the water, milk, brown sugar, butter, whisk together until combined.
Add the hook attachment and turn the speed to low and add in salt, yeast and flour 1 cup at a time until combined and knead the dough on low to medium speed for 5 minutes.
Add oil into a large bowl and place in the dough. Cover with a towel or lid and rest until it doubles in size.
Before it is time to form the dough, bring the baking soda and 4 cups of water to a boil in a large pot.
To form the dough, take a small piece and roll it out until it is a 24” long rope. Form the dough into a U shape and holding each end cross over each other and pull down to make a pretzel with the ends slightly over the other part of the dough. (See video below).
Turn down the boiling water to a simmer and cook each pretzel dough 1 to 2 at a time for about 30 seconds each and then place back on a cookie sheet tray lined with parchment paper.
Once all the pretzels have been cooked in the baking soda solution, brush the tops with the egg wash and season heavily with coarse salt or everything bagel seasoning.
Bake in the oven for 12 to 15 minutes or until golden brown.
