Divide the dough into 20 equal parts and knead each separately to form a small ball. Push a floured finger through the center of each and twirl it around your finger to make a bagel with about a 1 to 1 1/2" hole and an outer diameter of about 3". Let rise for 20 minutes.
Bring to boil 3 qts. water with 1 tablespoon sugar in it. Boil 4-5 bagels at a time for 4 minutes each, turning carefully. Dry on a paper towel. Mix the egg yolk with 1 tablespoon water, beat well, and brush the bagels with the mixture. Bake 20-30 minutes at 400oF (until brown). Don't expose to direct fire in the oven.
