Hornazo is a sort of Spanish meat pie eaten in the province of Salamanca, made with flour and yeast and stuffed with pork loin, spicy chorizo sausage and hard-boiled eggs. It is traditionally eaten in the field during the "Monday of the Waters" (Lunes de Aguas) festival.The name of this unique festival supposedly comes from a twisting of the word "enagua," or petticoat, which the prostitutes of the town used to wear under their dresses. During Lent, tradition tells us that the prostitutes of the town were sent to the other side of the Tormes River, so that the men of the town were not distracted during the religious observances. On this day, the Monday of the Waters, the students of the town threw a party on the banks of the river to celebrate the return of the women, and ate hornazo as part of the celebration.
