Please, Please, Please...

Do NOT muddy up your bowl of pho by dumping a bunch of hoisin into the broth...it just overpowers the whole thing and disrupts the delicate balance of herbs and spices. Sriracha is fine, but if you must insist, take an extra spoon and put your hoisin there, for dipping your meat. I like to mix it with some lime juice for an extra kick.
