These require less attention than latkes frying in a pan

Peel the potatoes and then Grate on the large holes of a box grater . Transfer to a fine-
mesh strainer and squeeze out as much liquid as possible into a bowl. Let the liquid settle for about 10 Minutes, and then pour off the watery liquid, reserving the potato starch.
Beat the egg white in a large bowluntil it holds a soft peak. Gently fold in the potatoes, scallions, reserved potato starch, 1/2
teaspoon salt and 1/4
teaspoon pepper.
Drop the mixture by
tablespoon on the prepared baking sheet, spacing the latkes about 2 inches apart. Gently spread and flatten into 2 1/2-inch rounds. Roast until the bottoms are browned, 8 Minutes to 10 Minutes. Flip and roast until the potatoes are cooked through and the bottoms are spotted brown, 4 Minutes to 6 Minutes.
