Wash hands with soap and water.

Preheat oven to 425 °F. Lightly grease 2 baking sheets.

In large bowl, sprinkle yeast over warm water (if water is too hot, it will kill the yeast). Stir until well blended.

Combine white and wheat flour in a separate bowl.

Stir in sugar, 1/2 teaspoon salt and 2-1/2 to 3 cups flour to make a soft, sticky dough. Turn dough onto well-floured surface.

To knead, fold dough in half and push dough flat with heels of hands. Turn dough 1/4 turn. Repeat for 5 to 7 minutes. If needed, add more flour until dough is smooth and elastic. Dough should not stick to hands or counter.

Cut dough into 12 even pieces (about golf-ball sized).

Roll one piece of dough into 15 inch long rope.

Cross left side over middle, creating loop.

Fold right side of rope up and over first loop to form pretzel shape.

Place pretzels 3 inches apart on baking sheet. Enlarge holes in pretzels by inserting finger into holes. This will prevent them from closing during baking.

In small bowl, mix egg and 1 tablespoon water together. Brush on pretzels. Sprinkle with sesame seeds.
