In large bowl, dissolve yeast in 2/3 Cup warm water. Let stand 5 minutes. Add 1 Cup flour, sugar, garlic salt and shortening; blend at low speed of electric mixer until moistened. Beat 3 minutes at medium speed. By hand, stir in an additional 1 - 1 1/2 Cups flour to form a soft dough.
Place dough in greased bowl; cover loosely with greased plastic wrap and cloth towel. Let rise in warm place (80° - 85° F) until light and doubled in size, about 30 - 40 minutes.
Grease 15" x 10" x 1" baking pan. On lightly floured surface, knead dough about 10 times or until no longer sticky. Roll into 15" x 10" rectangle; place on greased pan. Starting with 10" side, cut dough into 12 strips. Cut strips in half crosswise forming 24 sticks.
In a small bowl, combine 1 Tablespoon water and egg white; beat slightly. Brush over sticks. Sprinkle with sesame seed. Cover, let rise in warm place for 15-20 minutes.
Preheat oven to 375° F. Uncover dough. Bake 18-22 minutes or until golden brown. Immediately remove from pan; cool on wire rack for 5 minutes. Serve warm.
