8 hours before you plan to make the dough, feed your starter. I typically do 1/2 cup starter, 1/2 cup bread flour, and 1/2 cup water. Stir well and then lightly place a lid on top of the jar holding the starter so a little air can flow in and out.
When your sourdough starter is nice and bubbly, stir it well again and measure out 1/2 cup.
Add 1/2 cup bubbly starter and 1 1/4 cup water to your standing mixer with the dough hook. Start the mixer on slow and allow it to mix. While the mixer is still running, pour in all of the other ingredients: 1/2 tbsp fine sea salt, 1 tbsp granulated sugar, 4 tbsp olive oil and 4 cups of bread flour. Once a dough ball has formed, start a timer for 5 minutes and allow the dough to knead a full 5 minutes. Once done the dough should not longer stick to your finger when you poke it.
Remove the dough and place it in a large bowl with a lid. Cover the dough and leave it on the counter at room temperature for a bulk rise of 12-14 hours. I typically make my dough around 8 pm and come back at 8 am.
After a bulk rise, prepare a light-metal colored cookie sheet pan by lining it with parchment paper.
Separate the dough into 6 even pieces and shape the dough into pretzel shapes. Place the dough in the prepared cookie sheet pan and cover it with plastic wrap to rise for a second time of 2 hours.
After the second rise, preheat your oven to 400°F. While preheating, place a pot of water+ 1 tbsp baking soda on the stovetop over high heat. Once boiling, place each pretzel in and boil each side for 1-2 minutes. Place back on the pan and sprinkle with course sea salt.
Place the pan of pretzels in the oven and bake for 20 minutes. Remove, let cool for 15-20 minutes and enjoy!
