First, combine the softened cream cheese, crumbled bacon, chopped jalapenos, garlic powder, red pepper flakes, Monterey Jack, and cheddar cheese in a medium bowl. Mix everything until it's well-combined and smooth. Then, divide and shape the mixture into 12 small balls and place them in the refrigerator to firm up while you prepare the dough.
In a food processor, pulse the bread flour, yeast, salt, and sugar to combine them. With the processor running, slowly stream in the hot water until a smooth ball of dough forms. Continue to process for about 60 seconds to knead the dough. This method is much faster than kneading by hand.
Transfer the dough to a lightly greased bowl, turning it over once to coat the top. Cover the bowl with a clean kitchen towel and place it in a warm, draft-free spot. Let the dough rise for about 30 to 40 minutes, or until it has doubled in size.
Gently punch down the risen dough and divide it into 12 equal portions. Take one piece of dough and flatten it into a small disc. Place one of the chilled cheese balls in the center and carefully wrap the dough around it, pinching the seams tightly to seal it completely.
Place the shaped rolls seam-side down on a baking sheet. Cover them again with the towel and let them rise for another 20 minutes. This second rise ensures the rolls are light and puffy. While they rise, preheat your oven to 375°F (190°C).
In a large pot, bring 8 cups of water and the baking soda to a rolling boil. Carefully drop a few rolls at a time into the boiling water. Boil them for just 30 seconds on each side. This quick bath is essential for developing that classic pretzel crust.
Using a slotted spoon, remove the rolls from the water and place them on a baking sheet sprinkled with cornmeal. Brush the tops with the lightly beaten egg white, sprinkle generously with coarse salt, and top each with a slice of fresh jalapeno if desired. Bake for 25 minutes until they are a deep golden brown.
