The paste is a baked half-moon pastry made with wheat dough and a thick braided edge. The original filling is potato with ground or chopped meat, onion, parsley and black pepper, and it goes into the dough raw; the pastry is then sealed and baked. That is the main difference from empanadas, whose fillings are often cooked beforehand.
The story begins in 1824, when an English company took over the silver mines of Real del Monte and Pachuca and brought miners from Cornwall in southwest England. With them came the machines, football, the Methodist faith and the pasty, the pastry miners took into the shafts. According to tradition, they held the pastry by the braided edge, ate the rest and threw away the part touched by hands dirty with ore.
Over time the pasty became the paste and adopted Mexican flavors: in addition to potato and meat, there are mole, bean and other stew fillings, as well as sweet versions. Real del Monte was declared Cuna del Paste en México, has the Museo del Paste and hosts the Festival Internacional del Paste every October.
On the streets of Real del Monte and Pachuca, pasterías sell hot pastes straight from the oven, and many visitors take some to go.
