At first, mix up the sugar, water and kosher salt in a stand mixer bowl. Before mixing it up, spread the yeast. Now wait for almost 5 minutes to let it mix up until you see foam at the top of mixture.
Now use dough hook attachment to add butter and flour into the mixture and mix it up on a slow speed. Then gradually increase the speed to medium point for almost 5 minutes.
Then separate the dough from bowl and oil it with vegetable oil after cleaning the bowl.
You need to put dough back to the bowl. Properly cover it with a plastic wrap and put in on a warm place for 55-60 minutes. Keep watching until the dough gets doubled in size.
Now you need to preheat the oven to 450 degrees F and also use parchment paper to line 2 half-sheet pans. Give it a light brushing of vegetable oil.
Not take water, 10 cups, and baking soda and put in an 8-quart saucepan for a rolling boil.
Meanwhile, also get the dough out and place it on an oiled surface and divide it into 8 pieces of equal size.
Now you need to roll out each dough piece into the form of rope with 24-inch size. Then turn it into U shape by holding both ends of the rope. Now cross them and press them at bottom of U which will give them a perfect shape of pretzel.
Then put these pretzels into boiling water for almost 30 seconds and then remove them. Now brush each pretzel with water mixture and beaten egg yolk and sprinkle pretzel salt on it.
Now bake these pretzels for almost 15 minutes until you see the golden brown colour appears on the surface. Remove from the oven and cool it for 5 minutes. Serve these tasty soft pretzels and enjoy the party.
