Tucumana stalls set out a row of sauces and pickles, such as llajwa, onion-tomato salsa and pickled vegetables, and customers spoon them into the opened pastry between bites.
A half-moon pastry stuffed with seasoned beef or chicken, potato, peas and egg is deep-fried until golden and blistered. Street vendors in La Paz sell them hot each morning, splitting them open to fill with salsa.
