Creating soft pretzels is straightforward if you follow these well-defined steps:

1. Activate Yeast: In a large mixing bowl, combine warm water, sugar, and yeast. Let it sit for about 5-10 minutes until bubbly.
2. Mix Ingredients: Add salt and gradually mix in the flour, one cup at a time, until the dough begins to form.
3. Knead Dough: Transfer the dough onto a floured surface and knead for about 5-7 minutes, until smooth and elastic.
4. Let Dough Rise: Place the kneaded dough into a lightly oiled bowl, covering it with a damp cloth. Allow it to rise in a warm spot until it doubles in size (about 1 hour).
5. Prepare Boiling Solution: In a large pot, bring 10 cups of water and the baking soda to a boil.
6. Shape Pretzels: Once the dough has risen, punch it down and divide it into 8 equal pieces. Roll each piece into a long rope (about 20-24 inches), then twist into a pretzel shape.
7. Boil Pretzels: Carefully add each pretzel to the boiling baking soda solution for about 30 seconds, ensuring they are submerged. Remove with a slotted spoon and place on a baking sheet lined with parchment paper.
8. Apply Egg Wash: Beat the egg in a small bowl and brush the mixture over each pretzel. This step gives them a beautiful golden color when baked.
9. Sprinkle Toppings: Sprinkle coarse salt over the pretzels before baking.
10. Bake: Preheat the oven to 450°F (232°C) and bake the pretzels for 12-15 minutes or until they are a deep golden brown.
11. Cool: Allow the pretzels to cool on a wire rack for about 10 minutes before serving.
12. Optional Brush: For added flavor, brush with melted butter after removing from the oven.

By following these steps, you’ll be well on your way to enjoying homemade soft pretzels.
