First of all, be advised:
Tale spinning runs in my blood.
The correct term is:
Holy Moles!
Moles plural, pronounced Moh - lays, with reverence.
More on the moles below:
Mole ... is the generic name for a number of sauces originally used in Mexican cuisine, as well as for dishes based on these sauces. Outside of 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, pink Colorado (another name for red), green, almendrado, de olla, huaxmole and pipián.
However, when you speak of the "Holy Moles!" you are speaking of a specific beatified mole made with chocolate, or cocoa.
This is how the Holy Moles! came to be:
Era: Colonial time
Location: Convent of Santa Rosa in Puebla
Event: The poverty-stricken sisters of the convent learned that the archbishop intended to visit, and there was nothing in the pantry to feed the good man. "The nuns prayed and brought together the little bits of what they did have, including chili peppers, spices, day-old bread, nuts, and a little chocolate. They killed an old turkey, cooked it and put the sauce on top; the archbishop loved it. When the nun was asked the name of the dish, she replied, 'I made a mole.'"
I just know in my soul that two of the unnamed sisters were closely involved in the creation of the Holy Mole, singular, and I swear to God that their names were Sister Estrelila and Sister Carmelita.
