Yes, menudo is incredibly popular, and popular as a hangover cure.
My daughter’s best friend’s mom, Ramona, makes menudo frequently, and my daughter loves it. She asked Ramona what was in it, and Ramona just replied "Oh, pork and beef and spices." Half the great food I’ve had the first time has been explained away in a similar fashion. 😉
If you don’t have a friend-of-a-friend that makes it – go to almost any Mexican heritage festival (or in my experience, softball tournament) in the summertime in TX, and you’ll smell it simmering somewhere. Now, most of the folks I know wouldn’t exactly turn down a Corona (again, remember, this is a softball-tournament-connection LOL), but offer a Bud Light in exchange for a bowl and you’ll have friends for life. 😉
