Meanwhile, in large pot bring the 6 cups
water and 1 tablespoon sugar to boiling. Reduce heat. Add bagels, 4 or 5 at a time, and simmer for 7 minutes, turning once. Drain on paper towels. (If some bagels fall slightly, they may rise when baked.) Place on a well-greased large baking sheet. Mix the egg white and the 1 tablespoon water; brush over bagels. If desired, sprinkle with poppy or sesame seeds. Bake in a 375 degree F oven for 25 to 30 minutes or until tops are golden. Remove from baking sheets; cool on racks.
