Heat 170g of water and mix in 1 tsp of dry active yeast and 1 tsp of sugar. Allow the mixture to sit for 15 minutes until it becomes foamy.
In a bowl, combine 300g of flour, 1 tsp of salt, and 1 tbsp of olive oil with the yeast mixture. Mix until a dough forms.
Cover the dough and let it rise until it has doubled in size.
In a separate pot, prepare water with ¼ cup of baking soda and bring it to a boil.
Divide the risen dough into four equal pieces and roll each piece into a 24-inch long rope. Shape each rope into a pretzel by twisting and folding the ends.
Boil each pretzel in the baking soda water for about 15 seconds on each side, then remove them and let them drain well.
Arrange the boiled pretzels on a parchment-lined baking sheet and brush them with an egg wash.
Bake the pretzels in a preheated oven at 450°F for 20 minutes, or until they are golden brown.
For sweet pretzels, brush the baked pretzels with melted butter, then dip them in a mixture of 2 tbsp of sugar and ½ tbsp of cinnamon, shaking off any excess.
For salty pretzels, brush the baked pretzels with melted butter and sprinkle flaky sea salt on top.
