To understand whether Udon noodles contain egg, let's take a step back and look at their history. Udon noodles originated in Japan centuries ago and were initially made from wheat flour and water. The traditional recipe didn't include egg, and the noodles were known for their thick, chewy texture and neutral flavor.
Over time, however, some modern recipes for Udon noodles started including egg as an ingredient, particularly in Western countries. This was done to make the noodles more elastic and chewy, as well as to enhance their flavor. So, if you're buying Udon noodles from a store or eating them at a Japanese restaurant, there's a chance they might contain egg.
