Activate the Yeast
In a small bowl, combine warm water, a small pinch of brown sugar, oil, and yeast. Let sit for 5-10 minutes until foamy.
Mix the Dough
In a large mixing bowl, blend remaining brown sugar, flour (start with 4 cups), and salt. Pour in the activated yeast mixture. Mix until a rough dough forms, then knead for 8-10 minutes until smooth and elastic. Add more flour if too sticky.
First Rise
Lightly oil the dough ball and bowl. Cover and let rise in a warm place for about 1 hour, or until doubled in size. Don't punch it down.
Shape the Pretzels
Roll out dough on a lightly floured surface. Cut into pieces and roll into ropes. Twist into pretzel shapes.
Soda Bath
In a shallow, wide dish, dissolve 1/4 cup baking soda into warm water. Dip each pretzel briefly. Place on lined baking sheet.
Finish & Bake
Brush with eggwash. Top with coarse sea salt. Preheat oven to 450°F. Bake for 10 minutes, or until golden brown.
Optional Butter
Brush immediately with melted butter for that soft, buttery, mall-pretzel finish.
