Break off a piece of the dough and roll it into a long rope. Cut the rope into 2-3” long pieces. Put five pieces together to make a sea-star shape. Place the pretzels on a cookie sheet.
Lightly beat the egg in a bowl. Brush the beaten egg over the pretzels using a pastry brush. Sprinkle each pretzel with coarsely ground salt.
Bake pretzels at 400° F for 25 minutes.
