Therefore, if the noodles and the otsuyu are left together, the noodles will lose the otsuyu as time goes by, and eventually the otsuyu will run out. The noodles will stick together and become like dumplings, making them bad and inedible.
There is no way to restore the noodles to their original shape once they have stretched, but there is a way to prevent them from stretching. However, there is a way to prevent it from getting longer. If you keep the otsuyu and the noodles separate, they will last a little longer. However, the best way to eat ramen is to eat it freshly prepared right away.
