Sprinkle baking sheet with cornmeal. Working with one dough ball at a time, roll ball into a 8" cylinder shape, then flatten both ends (about 1" of cylinder) , form a tight spiral bring the two ends together to meet, overlapping forming a ring shape. Pinch and smooth out overlapping pieces and place on baking sheet. Wrap loosely again with plastic and repeat process until all bagels are formed. Leave about 1" in between bagels.

Using slotted spoon, transfer bagels to prepared wire rack, with cornmeal side facing down.Dip your bagels (side without cornmeal) into the toppings of your choice. Repeat.
