Instructions
Make the dough. Add the flour, salt, sugar, yeast, and warm water to the bowl of a stand mixer. Mix until the dough comes together, then knead with the dough hook for about 5–8 minutes, until the dough is smooth, soft, and elastic. You can also mix and knead the dough by hand.
Let it rise. Lightly oil a bowl, add the dough, cover, and let rise for 30 minutes.
Make the baking soda bath. While the dough rises, combine 1 cup very hot water with 2 tablespoons baking soda in a shallow pan or dish. Stir well and set aside. It does not need to stay boiling or even especially hot. By the time we're shaping pretzels, I want it comfortable to work around with kids.
Heat the oven. Preheat the oven to 475°F. Lightly grease a sheet pan or prepare it with your preferred nonstick liner.
Portion the dough. Divide the dough into 8 pieces for large pretzels or 16 for smaller ones. Let the pieces rest for about 5 minutes.
Make whatever you want. Roll the dough into ropes and twist into traditional pretzels—or don't! Make braids, balls, twists, letters, roses, or whatever your kids come up with. You can handle this dough quite a bit. If you don't like your shape, squish it together and try again.
Give them a baking soda bath. Place the shaped dough into the baking soda mixture and let it soak for about 2 minutes, spooning some of the water over the top if necessary.
Salt and rest. Transfer the pretzels to the prepared baking sheet and sprinkle with kosher salt. Let them rest, uncovered, for about 10 minutes.
Bake. Bake at 475°F for 8–9 minutes, or until beautifully golden brown. Stuffed or especially thick shapes may need a little additional time; watch the color rather than relying only on the clock.
Bring on the butter. As soon as the pretzels come out of the oven, brush them generously with all 6 tablespoons of melted butter. Yes, all of it. Keep brushing.
Serve warm.
