Night Before – Prepare the Starter At 10:00 PM, dissolve the 10g of sugar in 35g of water in a small jar.
Add 10g of sourdough starter and whisk together.
Stir in 70g of bread flour, mix well, form into a dough ball, cover, and let sit at room temperature (74–78°F) overnight until increased in volume by 2 or more times.
Mix & Proof the Dough In a mixing bowl, combine 100g of sweet stiff starter, 150g warm water, 270g bread flour, 27g sugar, 5g salt, and 2g malt (or 6g honey).
Knead for 5–10 minutes until well incorporated.
Add the 27g soft butter and continue to mix for a couple more minutes until gluten is developed.
Cover and let rise for about 3–4 hours until the dough becomes lighter and bigger with bubbles on the surface, performing a couple of folds during this time.
Shape & Chill Prepare a baking tray with generously oiled parchment paper.
Place the dough onto a non-floured work surface. Flatten it into a rectangle and divide it into 4 equal pieces (about 110–115g each).
Pre-shape the pieces as cylinders, then roll them into 20 cm long ropes.
Set the pretzel ropes on the prepared baking tray. Cover and let them proof for about 1 hour until puffy.
Move the proofed pretzel ropes into the refrigerator for 30 minutes to firm up for boiling.
Boil, Cut & Bake While the dough chills, bring 1 gallon of water to a boil in a wide pot. Add 3 tbsp baking soda and whisk well until dissolved. Preheat your oven to 425°F (220°C).
Remove the pretzel ropes from the fridge. Place 2 ropes at a time into the boiling water until they float (10 seconds or less), and cook for 20–30 seconds per side.
Using a slotted spoon, remove the ropes and place them back onto the oiled parchment paper. Let them cool for about 1 minute.
Use scissors to cut the boiled ropes into 1-inch thick bite-sized pieces directly on the oiled parchment paper.
Sprinkle with sea salt (optional).
Bake for 14–16 minutes until nice and brown.
Brush with melted butter while still hot for extra flavor!
