Continue beating, if necessary, until glossy and a small quantity of dough scooped on the end of a spoon stands erect.
For cream puffs: Drop dough by scant 1/4 cupfuls, about 2 inches apart onto ungreased baking sheet. For éclairs: Shape scant 1/4 cupfuls into 4 x 1-inch fingers on ungreased baking sheet. Bake in lower third of 425 degrees oven until lightly browned, about 20 minutes. Reduce oven settingto 375 degrees. Continue baking until firm and golden brown, about 20 minutes longer. Immediately after baking, pierce side of each puff with tip of sharp knife. Cool on wire rack.
