Place 2 quarts of water and 2 ½ oz baking soda in a large pot and bring it to a boil while shaping the pretzels.
Preheat the oven 425 °F. Line 2 baking sheets with parchment paper and coat the parchment paper with vegetable oil.
Turn the dough out onto a floured surface and divide into 12 equal pieces.
Shape each piece into a rope. Using flat hands, roll the dough back and forth moving your hands in opposite directions from the middle of the rope towards either end. If the dough gets sticky dip your hands in flour and continue. The dough should stick to the surface just a little so that the friction will allow you to pull the dough into a long rope. The longer and thinner the rope the more open the pretzel shape will be. Try to get the rope to about 20"-24"
To form a pretzel lift the dough rope on either end and allow the middle to sit on the surface, forming a "U" shape. Twist the ends of the rope together 2x and fold the twist over and rest on the center of the "U". Lift the pretzel by the two top loops and place on the oiled parchment paper.
Once the baking soda water is boiling dip the pretzels into the water for about 10 seconds per side. (I can fit about 3 at a time in my pot, don't overcrowd the pan).
Set the boiled pretzels onto a cooling rack and allow them the drain while you boil the remaining pretzels.
Transfer the pretzels to the baking sheets (lined with oiled parchment). Brush each pretzel with egg white and sprinkle with pepitas and coarse salt.
Bake until puffed and golden brown, about 15 minutes, turning the sheets halfway through baking so they brown evenly.
Enjoy them warm with dip.
