you're not supposed balance the pickles on edge you retard
For real, though, the reason people gush over 3rd-world food is because they didn't have near-universal fridges and freezers until recently. Low-tier food in the USA is pretty much all frozen, canned, or processed to be shelf-stable. Think gas station hot dogs, McDonald's, that sort of thing. Even mid-tier can be absolute shit, like Carabba's and Olive Garden serving serving week-old frozen chicken and box pasta, or Applebee's end-to-end disgusting menu.
By contrast, a street taco in Mexico still has a fresh tortilla and fresh meat that was cooked today. (Might be cat, but still.) A fresh, cheap cut of beef and a fresh, simple flour-and-water tortilla are miles better than a bun that's been sitting in a bag for five days and freezer-burned ground beef.
It's not so much that we "can't" do that, it's that we got culturally used to everything being ultra-processed in the postwar era. Which, ironically, most Mexican restaurants here use stale, bagged tortillas because Americans think it's okay to pay $25 for a meal with stale bread.
