Press the fold into place, creating a rounded edge. Run your fork between the edge of the pan and the far edge of the omelet to loosen. Using the palm of one hand, tap the handle gently where it joins the pan, to shake the omelet and make it twist and lift onto itself, so the lip rises above the edge of the pan. Fold this lip back toward the center of the omelet, meeting and overlapping the edge of the other lip.
