In Colombian Spanish, 'aborrajar' simply means to coat something in batter before frying, so the snack is named after how it's cooked.
Ripe plantain is sliced, sandwiched around a slab of soft cheese, dipped in an egg batter, and deep-fried until golden. Street stands across Cali sell them hot in paper, often alongside guava paste.
Why it's made this way: Valle del Cauca's plantain plantations make the fruit cheap and abundant, and Cali's street-food scene turned the sweet-savory combination into one of its most recognized fried snacks.
