The name is half Hindi: aloo is the Hindi and Bhojpuri word for potato, a legacy of Trinidad's Indian indentured laborers.
A ball of seasoned mashed potato is enclosed in dough and deep-fried into a puffed, golden pastry, split open and filled with tamarind sauce, chutney, and pepper at roadside stands.
Why it's made this way: Along the Diego Martin approach to Maracas Bay, aloo pie vendors set up as the savory, meat-free counterpart to the beach's famous shark sandwiches.
