In a stand mixer combine the sugar, yeast, and warm water. Stir lightly and let sit for about 5 minutes or until frothy.
Add your melted butter
In a separate bowl combine your flour and salt.
Using your dough attachment, mix in your flour slowly. Once combined increase your speed to medium high to knead your dough.
Transfer your dough to a lightly oiled bowl. Cover with a towel and keep at room temperature for about an hour or until the dough doubles in size.
Cut your dough into 16 even pieces. Then roll each piece out into about a 6 inch snake or log form. Then knot each piece by putting end in through the center and then pinching both ends together.
Let the knots rest again for about 30 minutes for a second rise.
Pretzel Tops
Boil the water and add your baking soda. Mix until dissolved. Set aside to cool.
Place your pretzel knots in this solution and let sit for 5 minutes.
Line baking sheets with parchment paper and oil. Pre-heat oven to 425 degrees F.
Place knots on the baking sheet. Brush each knot with your egg wash and then sprinkle with your coarse salt.
Bake pretzel knots for 12 minutes.
Beer Cheese Sauce
In a sauce pan melt your butter and add your flour. Whisk together for a few minutes.
Add your cayenne pepper, onion powder, garlic powder, and mustard.
