"A churro, sometimes referred to as a Spanish doughnut, is a fried-dough pastry-based snack, sometimes made from potato dough, that originated in Spain. Churros are also popular in Latin America, France, Portugal, Morocco, the United States, Australia, and Spanish-speaking Caribbean islands." (From Wikipedia)
This was all news to me. I had no idea it originated in Spain, all i know is that for years it smelled like end of class snack after high school, while waiting for my granddad to pick me up... Sometimes while watching the frequent summer rains in Rio, or watching the other kids play with never ending energy, it was my constant companion during my childhood.
