Dissolve yeast in the lukewarm water.
Mix flour and salt together in a large mixing bowl.
Form a well in the flour mixture then add the sugar to the center of the well.
Pour the yeast/water mixture into the well.
Let it rest for 15 minutes before mixing.
Add the softened butter to the mixing bowl and knead everything to a smooth dough.
Remove the dough hook and let the dough rest for 30 minutes.
Cut the dough into twelve equal parts, then roll each piece on the table to about 20 inches, tapered toward the ends.
To form the pretzel shape, place dough rope on parchment lined cookie sheet so that it creates the shape of the letter 'U'.
Take both ends of the 'U' and cross them over each other twice forming a twist.
Bring that twist down and place it over the bottom curve of the 'U'.
Place the pretzels without covering them in the fridge for about an hour.
Preheat the oven to 400 F.
Fill large stock or pasta pot ¾ full and bring the water to a boil.
Carefully and slowly add the baking soda to the boiling water.
Using a slotted spoon, gently drop each pretzel into the bath for 10 seconds, then turn over for another 10.
Place them on a baking sheet lined with parchment paper.
Score the dough once like for a baguette with a razor blade or sharp knife.
Sprinkle with coarse salt.
Bake the pretzels for about 15 to 20 minutes.
