'Shuco' is Salvadoran slang for 'dirty,' a nod to the drink's murky grayish-purple color rather than to how it's made.

Atol shuco is made by fermenting black or purple corn dough for a couple of days, then cooking it into a thick, sour, savory drink topped with whole beans, ground toasted pumpkin seed (alguashte), salt and chili. It's sold hot by street vendors in the early morning and evening, traditionally served in a gourd bowl called a huacal and drunk without a spoon.

Why it's made this way: The deliberate fermentation and tangy flavor make it one of the most distinctive corn drinks in the region, tied specifically to El Salvador's working-class street food culture.
