You can make it yourself.
I might have a bud send me a bottle or two of "Pico Pica"
or some similar sauce.
You can tell that you have the genuine article here in the SW
if the product is described as "hot sauce".
There was a time, not too long ago, when the term "hot sauce"
was rather left behind for all the new formulations that the ever
changing marketplace of Capitalism requires. Hence "Chunky"
"Salsa", "Piquante", "Verde", and all of the other new adjectives.
Nowadays, one has to reach over these versions to find the classic
roasted red chili flavor.
LOL, then get tortillas. I spent waaay too long trying to find them
in a grocery store in West Virginia before I found them, with the
other breads, under the name "Wraps". LMAO.
The rest is easy. Can you get Cilantro? Chop it with tomatoes,
onions, garlic if desired, and a squeeze of lime. Let *that* stuff
sit in the fridge for an hour and anything you put it on will say
"Hola Amigo".

Take care,
