Kaiser Rolls

2 packages (1/4 ounce each) active dry yeast
2 cups warm water (110° to 115°), divided
4 tablespoons sugar, divided
1/3 cup vegetable oil
2 teaspoons salt
6 to 6-1/2 cups all-purpose flour
1 egg white
2 teaspoons cold water
Poppy and/or sesame seeds
DIRECTIONS In a mixing bowl, dissolve yeast in 1/2 cup warm water. Add 1 tablespoon sugar; let stand for 5 minutes. Add the remaining warm water and sugar. Beat in oil, salt and 4 cups flour until smooth. Stir in enough remaining flour to form a soft dough. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour. Punch dough down. Turn onto a lightly floured surface; divide into 16 pieces. Shape each into a ball. Place 2 in. apart on greased baking sheets. Cover and let rise until doubled, about 30 minutes. Beat egg white and cold water; brush over rolls. Sprinkle with poppy and/or sesame seeds. With scissors, cut a 1/4-in.-deep cross on tops of rolls. Bake at 400° for 15-20 minutes or until golden brown. Remove from pans to wire racks to cool. Yield: 16 rolls.
