Armar el trompo
Armar el trompo (or armar la bola) is the taquero's term for building the stack of marinated, thinly sliced pork on the vertical spit used for tacos al pastor, a job done before service that determines how evenly the meat will cook.
The bola
The cone of meat on an al pastor spit is called the bola. Lesley Téllez, reporting for PBS SoCal, explains that putting it together is known as armar la bola, and that it is part of the pastorero's job, along with trimming the ends so the stack cooks evenly. The thin fillets of pork are first marinated and then threaded on the spit layer by layer; Luz Noticias lists filleting and marinating the meat that goes onto the trompo among the basic skills of the trade.
Why it matters
The way the stack is built affects how evenly it cooks. Téllez notes that the pastorero must watch the stack, turn it, and adjust the heat as the bola grows smaller.
Learning to build it
Taqueros describe it as one of the hardest parts of the job. In a POSTA México report from July 2026, a young cook at the Mexico City taquería El Gallo named shaping the trompo, along with making every order come out the same, as his biggest challenge, and Mauricio Luna of Tradición Chilanga said no one teaches how to build the pastor stack, so cooks learn by watching their colleagues.
