Combine the water and sugar in a small bowl.
Sprinkle the yeast on top. And gently stir to incorporate.
Allow the mixture to sit for 5-10 minutes until foamy.
To the bowl of a stand mixer, add the flour, salt, and butter.
Add the foaming yeast mixture.
Using the dough hook attachment, mix at low speed until combined.
Switch to medium speed and knead the dough for about 5 minutes.
Remove the dough from the mixer bowl, oil the sides, and return the dough.
Cover the dough and put in a warm (75-90°F) area for about 60 minutes, or until doubled in size.
Preheat the oven to 450°F. Line 2 half-sheet pans with parchment paper and lightly brush with the vegetable oil. Set aside.

In a heavy bottomed non-corrosive pot (think ceramic), bring 10 cups of water and the baking soda to a rolling boil.
While waiting for the oven to preheat, and the water to boil, turn the dough out onto a slightly oiled work surface and divide into 8 equal pieces.
Roll each piece of dough into a 12-18 inch rope.
Cross the dough in half, like you would when tying your shoes, knot, and tuck the loose ends under to create a ball.
Repeat for each piece of dough.
Place the pretzels into the boiling water, 1 by 1, for 30 seconds.
Remove the knots from the water using a large slotted spoon or wire skimmer.
Place each onto the baking pans, spread equally apart.
Brush the tops of each with beaten egg yolk, and sprinkle with pretzel salt.
Bake 12-15 minutes until a dark golden brown.
Cool for at least 10 minutes before serving.
