Of course I cracked the code to street food already! Im not gonna waste precious pesos paying someone else to make us junk food!!
Doritos (nacho or the black spicy bag)
Peanuts (Japoneses if you are in MX)
Salsa Valentina or Botanera
Miguelito (the powdered chili mix)
Feel free to add or leave out as you see fit. They sell them with cuervitos (thats not the right word... But we dont eat them so I can never remember the word- the white jelly slimy things?) and also right in the Dorito bag here in good ole Mexico City.
May I add my inlaws have had these things their whole lives and I had my first bag this past month and have already replicated them at home? Yes, the inlaws approved of my copy cat version. I win again!
