Thank you to David W. who found this recipe for me.
Since I didn't have the full six cups of flour the original called for, I cut the recipe in half. I also used my bread machine to make the dough, saving a lot of work for me.
The rolls turned out just perfect!
2 1/4 t (1 pkg) active dry yeast
1 cup warm water, divided
2 T sugar, divided
3 T canola oil
1 t salt
3 cups flour
1 egg white
1 t cold water
In bowl of bread machine, dissolve yeast in 1/4 cup warm water; let rest 10 minutes or til frothy. Add 1/2 T sugar; let stand another 5 minutes.
Add the oil, salt, remaining warm water, sugar and flour. Process on dough cycle. Keep an eye on dough for first few minutes. If dough appears dry, add a bit more water. If dough appears too wet, add more flour.
Remove dough from bread machine and turn out onto a lightly floured surface; divide into 8 pieces. Shape each into a ball. Place about 2 inches apart on a large baking sheet that has been sprayed with cooking spray. Cover and let rise til doubled, about 1 hour.
Preheat oven to 400°.
Beat egg white and cold water; brush over rolls. With scissors, cut a 1/4 inch deep cross on tops of rolls. Sprinkle with poppy seeds.
Bake 15-20 minutes or til golden brown. Remove rolls from pans to wire racks to cool.
Slice in half before filling.
