Combine water, yeast and sugar into the bowl of a stand mixer. Let sit 5 minutes until yeast is foamy.
1 ½ cups warm water, 1 packet rapid rise yeast, 1 tablespoon brown sugar
Then add butter and salt. Mix with dough hook. Add in 2 cups of flour and mix on low for 2 minutes. Scrape down the sides and add remaining flour. Scrape down sides again. Mix on low until dough pulls away from bowl and is tacky but not sticky. If sticky, add more flour ¼ cup at a time. Then mix on low for 2-3 minutes or knead by hand for the same amount of time.
Add water and baking soda to a large pot and bring to a boil. Beat egg in small bowl with water. Line two large baking sheets with parchment or silicone baking mats. Preheat oven to 400.
8 cups water, ¼ cup baking soda, 1 egg
Lightly flour a surface and turn out dough. Roughly divide into 8 pieces, working with 2 at a time. Set remaining pieces aside and cover with a towel. Form dough into an oblong shape in your hands, then place on the floured surface and use both hands rolling the dough back and forth until its a rope about 1.5 inches thick. Cut into 2 inch pieces with a pizza cutter, bench scraper or knife. Place on baking sheet and repeat with all dough.
Carefully lower pretzel dough pieces into the boiling water with a slotted spoon for 15 seconds. Remove, draining excess water and placing back onto the baking sheet. Repeat with all pretzel dough.
Space out dough bites and brush with egg wash. Sprinkle kosher salt (or alternate toppings) on top. Bake for 12-15 minutes until golden. Serve warm.
