Heat the milk to 105-110°F in a large measuring cup or bowl.
1½ cups warm milk
Add the yeast to the milk and stir and allow this to sit for a few minutes so the yeast can bloom.
2¼ teaspoons dry-active yeast
Add the milk mixture to the bowl of a stand mixer along with the brown sugar, melted butter, and salt.
1 Tablespoon light brown sugar, 1 Tablespoon salted butter, 1 teaspoon salt
Add the flour to the milk mixture, 1 cup at a time, mixing with a dough hook between each addition until the dough is no longer sticky (you may not need to use all 4 cups). Then turn it out onto a floured surface and knead it for 5 minutes by hand.
4 cups all-purpose flour
Shape the dough into a ball and place it into a large lightly oiled bowl. Cover it with plastic wrap and allow it to rest for at least 10 minutes.
1 tablespoon vegetable oil
While the dough is resting, preheat the oven to 400°F, line 2 baking sheets with parchment paper and lightly spray the sheets with nonstick spray. Set aside.
Bring the water and baking soda to a boil in a large pot.
8 cups water, ⅓ cup baking soda
Cut dough into 10 equal pieces (use a kitchen scale for accuracy) and shape each piece into 18-inch-long ropes. Shape the ropes into pretzels. Press the ends in to make sure they are stuck down. Here's a video showing how to twist pretzels. Use a slotted spoon to dip each pretzel in the baking soda water for about 30 seconds. Then allow the water to drip off of the pretzel and place it on the baking sheet lined with parchment paper. Repeat with each pretzel then sprinkle them with sea salt.
¼ cup coarse sea salt
Bake at 400°F for 15 minutes or until golden. While these are baking you could make our cheese dip recipe.
