In Central America , quesillo refers to a dish typically made from a thick corn tortilla wrapped around soft cheese (with the same name and of consistency similar to mozzarella cheese), pickled onions, and a sauce of sour cream or liquid cheese and vinegar.[1] Originally from the León Department, there is a great dispute as to where they were invented. They are often sold on roadsides as a quick snack or in the street by quesilleras, women who sell quesillos.
A popular pun of this locale is to alter the phrase claro que si, meaning “of course”, into claro quesillos. Because of their runny contents, quesillos are usually confined by a thin plastic sheath. Often the plastic bag is tied off, a small corner is bitten off, and the quesillo is squeezed out of a small hole in the corner.
