Steps

mix the dry ingredients together. Make a well, add the water, and mix together. Develop the dough using the stretch and fold method with 15-minute intervals, repeating until the dough passes the window pane test

Let it rise at room temp for 30 minutes

While the dough is rising, boil water with baking soda and set the mixture aside to cool to lukewarm (or cooler)

Transfer the dough to a lightly greased work surface, and divide it into four equal pieces (about 70g each) and all the pieces to rest, uncovered, for 5 minutes

Roll each piece of dough into a long, thin rope (about 28" to 30" long), and twist each rope into a pretzel shape. Place them in the pan with the baking soda/water and let them rest for 1 minute on each side before placing them on the baking sheet. This baking soda bath will give the pretzels lovely golden-brown color.

Transfer the pretzels to the prepared baking sheet. Sprinkle them lightly with coarse, kosher, or pretzel salt. Preheat the oven to 475 and allow them to rest, uncovered, for 10 minutes

Bake the pretzels for 8 to 9 minutes, or until they're golden brown. Remove the pretzels from the oven, and brush them thoroughly with the melted butter and top with flaky salt
