Mole (/ËmoÊleÉª/, /ËmoÊli/ Spanish pronunciation: [Ëmole]; from Nahuatl mÅlli, sauce) is the generic name for a number of sauces originally used in Mexican cuisine, as well as for dishes based on these sauces. Outside Mexico, it often refers specifically to mole poblano. In contemporary Mexico, the term is used for a number of sauces, some quite dissimilar, including black, red, yellow, Colorado (another name for red), green, almendrado, de olla, huaxmole and pipiÃ¡n.
The number of elementary entities in a sample of a substance is technically called its (chemical) amount. Therefore, the mole is a convenient unit for that physical quantity. One can determine the chemical amount of a known substance, in moles, by dividing the sample's mass by the substance's molar mass.
