Cuerito is pig skin (pork rind) from Mexican cuisine, Venezuelan cuisine and Spanish cuisine. Cuero is the Spanish-language word for leather or hide, so cueritos means "little leathers". They are usually pickled in vinegar (cueritos de vinagre) and can be made with a spicy sauce. The vinegar can be seasoned with pineapple, dulce macho (piloncillo), cloves, peppercorns, chile de árbol and oregano. Yummy
