In a small bowl, combine the water, dry yeast, and sugar. Let it stand for 5 minutes to allow the yeast to activate. It will get foamy on the top if the yeast is live, if it doesn't get new yeast and start over.
1½ cup warm water, 2¼ teaspoon dry active yeast, 2 tablespoon sugar
In a large bowl, combine the flour, salt, yeast mixture, and melted butter. Mix well.
4¼ cup bread flour, 1 tablespoon salt, 2 tablespoon butter
Once the flour mixture forms a shaggy ball, pull the dough out and knead it for five minutes on a floured surface.
Using a little flour, shape the ball of dough into a square about 9" x 9".
Cut down the middle, then cut across both halves six times for 12 equal sections.
Roll out each of the twelve portions of dough into 8-9" length ropes.
Place parchment paper on two rimmed baking sheet and spread six dough ropes on each, keeping distance apart so the dough can rise.
Cover the breadsticks with a towel and let the dough bulk proof (rise for 45 minutes.
In a small bowl, mix the remaining melted butter, garlic salt, and dried parsley flakes. Using a pastry brush, brush the breadsticks with half the mixture.
¼ cup butter, 1 teaspoon garlic salt, 1 teaspoon dried parsley flakes
Preheat oven to 400℉ (204℃) and bake breadsticks for 12 minutes, or until light golden brown. Remove from one and immediately brush with the remaining garlic butter. Serve while hot.
