Heat 1 cup water and shortening until about 120℉ (it should feel warm on your wrist, but not hot). Add sugar and yeast and stir until dissolved. Let yeast proof for a few minutes (become bubbly)
1 tablespoon sugar, 1 packet active dry yeast, 1 cup water, 1 tablespoon shortening
In a large bowl combine flour, salt and crumbled bacon pieces. Add yeast mixture and blend at low speed until moistened, then beat 3 minutes at medium speed.
2 ½ - 3 cups bread flour, 1 teaspoon salt, ⅓ cup crumbled bacon pieces
Stir in additional 1 ¼ to 1 ½ cups flour until dough pulls cleanly away from the bowl.
On a floured surface knead in ¼ cup to ½ cup flour for about 10 minutes until dough is smooth and elastic.If you have a mixer with a dough hook, let it do the work and knead for about 5 minutes.
Clean the large bowl and grease it. Place the dough in the bowl, cover and let rise until doubled in bulk about 45-60 minutes. I turn my oven to the lowest setting then turn it off and put the bowl in while rising.
Punch down dough to remove all air bubbles. Let rest 10 minutes.
Divide dough into 12 pieces. Roll into long ropes and shape like a pretzel, or cut into small "pretzel bites". Place on greased baking sheet. Let rise until light, 15-20 minutes.
Preheat oven to 400℉. In a large saucepan, bring water and baking soda to a boil.
6 cups water, 2 tablespoons baking soda
Add pretzels gently to the boiling water 2-3 at a time. Flip after 10-15 seconds and boil another 10-15 seconds. If you like them with extra pretzel taste, boil 30-45 seconds a side.
Remove pretzels with a slotted spoon and return to the baking sheet. Combine egg white with 1 tablespoon water and brush on pretzels. Sprinkle with parmesan cheese.
1 egg white, ¼ cup parmesan cheese
Bake for 8-10 minutes depending on desired level of brownness.
Notes
You can substitute all purpose flour for the bread flour, but you may want to knead and let them rise a little longer to have the same light chewy texture.
