A noole is made from unleavened dough that has been shaped into thin flat strips or round cylinders and cooked in a boiling liquid. Depending upon the type, noodles may be dried or refrigerated before cooking. The word noodle derives from the German Nudel (noodle) and may be related to the Latin word nodus (knot). In English, noodle is a generic term for unleavened dough made from many different types of ingredients and includes a variety of shapes.
