Creating cheese-stuffed pretzels involves a few straightforward steps. Let’s break it down:

1. Activate Yeast: In a large bowl, combine warm water, sugar, and yeast. Let it sit for about 5 minutes until foamy.
2. Mix Dry Ingredients: In another bowl, mix the flour and salt.
3. Combine Mixtures: Add the melted butter to the yeast mixture. Gradually add the dry mixture, stirring until a dough forms.
4. Knead the Dough: On a floured surface, knead the dough for about 5-7 minutes until smooth.
5. Let it Rise: Place the dough in a greased bowl, cover it with a towel, and let it rise for about 1 hour or until doubled in size.
6. Preheat Oven: Preheat your oven to 425°F (220°C).
7. Prepare Baking Soda Solution: In a large pot, bring 10 cups of water and baking soda to a boil.
8. Shape Pretzels: Roll the dough into a long rope (about 12-14 inches). Flatten it slightly and place a tablespoon of cheese in the center. Fold the dough over the cheese and twist to form a pretzel shape.
9. Boil Pretzels: Carefully drop shaped pretzels into the boiling water for about 30 seconds. Use a slotted spoon to remove and place on a greased baking sheet.
10. Egg Wash: Brush each pretzel with the beaten egg, then sprinkle with coarse salt.
11. Bake: Bake in the preheated oven for 20-25 minutes, or until golden brown.
12. Cool and Serve: Allow pretzels to cool slightly before enjoying. Serve with your favorite dipping sauce!
