The cemita is a torta originally from Puebla, Mexico. The name can refer to the bread roll it is served on as well.
The cemita, also known as cemita poblana, derives from the city (and region) of Puebla. The word refers to the sandwich as well as to the roll it is typically served on, a bread roll covered with sesame seeds. The bread is made with egg, and resembles brioche. Additionally, the ingredients usually are restricted to sliced avocado, meat, white cheese, onions, the herb pápalo and red sauce (salsa roja). In modern times it has appeared on the streets of New York, Los Angeles, and other cities with Mexican food vendors.
The most popular meat in a cemita is beefmilanesa, a thinly pounded and deep-fried piece of beef. Cueritos (pickled pig skin), queso de puerco (pork head cheese), and carnitas (stewed pork) are also popular. The cheese is often panela, a bland white cheese with the consistency of fresh mozzarella. Quesillo, a Mexican string cheese, is also used.
Although the name is the same, there are diverse types of cemitas depending on the region. The cemita of Sahuayo, Michoacán, is a smooth bread, without sesame seeds and including piloncillo. Its flavor is somewhat sweet and very flavorful; usually it is accompanied by a glass of milk, a corn flour drink (atole), or some sort of hot drink. It is not used like a sandwich.
