Just what is a "real" noodle? A noodle is often defined as the result of flour mixed with eggs. But, there are many noodle-esque noodles made without one or both of those ingredients -- like noodles made from agar-agar (dried seaweed) or from strips of bean curd; or Chef Nobuyuki Matsuhisa's squid noodle-invention. They're "noodles" made from squid alone. All still noodles? Sure. "Real" noodles include Asian noodles, such as cellophane noodles, made from mung-bean flour; rice ribbon noodles, made rice flour; western dried pasta, made from semolina -- the list could go on and on. A "real" noodle, then, is made from combining some kind of flour with some kind of wet mixing agent. Try to come up with anything more specific than that and there will be thousands of would-be noodles protesting at your door.
