# Components:
→ Dough
01 - 1 cup active sourdough starter at 100% hydration
02 - 2.5 cups bread flour
03 - 2/3 cup warm water
04 - 2 tablespoons unsalted butter, melted
05 - 1 tablespoon granulated sugar
06 - 1 teaspoon fine sea salt
→ Onion Mixture
07 - 1 medium yellow onion, finely diced
08 - 1 tablespoon olive oil
09 - 1/2 teaspoon salt
→ Baking Soda Bath
10 - 6 cups water
11 - 1/4 cup baking soda
→ Topping
12 - 1 egg, beaten for egg wash
13 - Flaky sea salt for sprinkling
14 - Minced chives or dried onion flakes, optional
# Directions:
01 - Heat olive oil in a skillet over medium heat. Add diced onion and 1/2 teaspoon salt, stirring occasionally until golden and caramelized, approximately 12 to 15 minutes. Transfer to a plate and allow to cool completely.
02 - In a large mixing bowl, combine sourdough starter, bread flour, warm water, melted butter, sugar, and 1 teaspoon salt. Mix until a shaggy dough forms.
03 - Add cooled caramelized onions to the dough. Knead by hand or with a dough hook for 7 to 10 minutes until smooth and elastic.
04 - Place dough in a lightly greased bowl. Cover and let rise in a warm place for approximately 2 hours, or until doubled in size.
05 - Preheat oven to 425 degrees Fahrenheit. Line two baking sheets with parchment paper.
06 - Turn dough onto a floured surface and divide into 4 equal pieces. Roll each piece into a 12-inch rope, then cut each rope into 1-inch pieces.
07 - Bring 6 cups water to a boil in a large pot. Carefully add baking soda, which will bubble. Working in batches, drop pretzel bites into the boiling water for 30 seconds. Remove with a slotted spoon and arrange on prepared baking sheets.
08 - Brush each bite with beaten egg. Sprinkle with flaky sea salt and optional toppings.
09 - Bake for 12 to 15 minutes, or until deep golden brown.
10 - Allow to cool slightly before serving warm.
