Stir sugar into 1/4 cup warm water in a small bowl. Sprinkle yeast over top. Let stand for 10 minutes; stir to dissolve yeast.
Combine 1 1/2 cups warm water, flour and salt in large bowl. Stir yeast mixture in. Add a bit more flour, if needed, so dough isn't too sticky.
Knead for 8-10 minutes until dough is smooth and elastic.
Place in greased bowl, turning once to grease top. Cover with tea towel and let stand in oven with light on and door closed for 45 minutes, or until doubled in bulk.
Punch dough down and roll into a log. Divide into 12 portions. Roll each portion into 1/2 inch rope. Shape each rope into pretzel form on greased baking sheets.
Beat egg white and 1 teaspoon water with fork in small bowl; brush glaze on pretzels. Sprinkle pretzels with kosher salt, sesame seeds or cinnamon sugar.
Bake at 450 degrees F for 12-15 minutes.
