Because cassava noodles (mien) are very chewy in texture and very filling, mien ga should not be served in the same proportion as a bowl of pho. Besides the texture play of cassava noodles and tree ear mushrooms, this soup is sweeter than other Vietnamese chicken soups or canh consommés because of the daikon and carrots. If you do not want to make the chicken stock from scratch, use 8 cups of unsalted chicken broth. Vietnamese coriander gives a nice pungent and bitter bite to the soup. You can’t have the soup without it. The acidity of the lime adds a nice and simple zing.
