Step 1

Bring a pot of water to a boil. Preheat the oven to 425 degrees F. Spray a baking sheet with cooking spray and set aside.

Step 2

Roll each dinner roll into a long rope approximately 1 1/2 to 2 times the length of a hot dog. Coil each rope around a hot dog, pinching the ends to seal them so they cannot come loose.

Step 3

Add the baking soda to the boiling water, then, working in batches, drop the pretzel dogs into the water for 30 seconds and remove to a rack.

Step 4

When all the dogs have been boiled, place them on the greased baking sheet. Brush with the beaten egg and sprinkle with pretzel salt.

Step 5

Bake until the bread ropes are cooked and have turned golden brown, about 12 minutes. Serve with spicy mustard and pickles.
