Tamales are one of the most popular street foods in the world. They feature a filling and are wrapped in corn-based masa dough and steamed in corn husks. Tamales come in sweet and savory versions, some spicy and some bland. Versions with pork or chicken with a salsa or mole sauce are the most popular, along with a version called "rajas" that are filled with strips of poblano chili pepper and cheese. It is one of the safer street foods for novices to try as it is cooked and kept in a steam vat while being sold. Corundas are a variety of tamale in Michoacán in a triangle shape wrapped in corn stalk leaves. They can be eaten alone, with salsa or as an accompaniment to a meal. The Chiapas version of the tamale has a distinct flavor, often containing ingredients such as pibil, mole sauce, carrot, corn grains, egg, raisins, almonds (known locally as nacatamales, a regional version of Nicaraguan well-known version), a version with the regional herb chipilín with chicken or queso blanco and versions wrapped in banana leaves. They are often sold by vendors on specially made tricycles for street vendors. Uchepos are tamales made with fresh corn, generally made in Michoacán in July and August.
