Step 1

Preheat the oven to 425°F (218°C). Line a large baking sheet with parchment paper or a silicone baking mat and set aside.

Step 2

In a large mixing bowl, whisk the warm water and sugar together. Gently stir in the yeast and allow to stand for 5 minutes until foamy.

Step 3

Add the melted butter and salt to the mixture and stir until fully combined.

Step 4

Mix in 2 cups (250 grams) of flour until just combined, then mix in 1 more cup (125 grams) of flour until just combined. Add more flour if needed until the dough is thick and no longer sticky.

Step 5

Place the dough on a lightly floured surface and knead for 3 to 5 minutes, then shape the dough into a ball.

Step 6

Cover the dough and allow it to rest for 10 minutes.

Step 7

Pour 9 cups of water into a large pot over high heat, add the baking soda, whisk until well combined, and bring to a boil.

Step 8

Using a knife, divide the dough into 8 equal pieces. Roll out each piece into a rope about 20-inches in length.

Step 9

Take the ends of each rope and create a U-shape. Twist the ends over each other then press them onto the bottom of the U to form the pretzel shape.

Step 10

Using a slotted spoon or spatula, gently dip each pretzel into the boiling water for 20 seconds (10 seconds on each side). Gently lift the pretzel out of the water and allow any excess water to drip off.

Step 11

Transfer the pretzels to the prepared baking sheet. Brush with the melted butter and top with coarse sea salt.

Step 12

Bake for 8 to 10 minutes or until baked through then turn the oven to broil and bake for 2 to 3 more minutes or until the tops are brown (be sure to keep a close eye on them so that they don't burn).

Step 13

Remove the pretzels from the oven and brush with any remaining butter.

Step 14

Allow to cool slightly and serve warm.
