What is a cortado?

A Cortado is a coffee beverage consisting of espresso "cut" with a small amount of warm milk to reduce the acidity. The ratio of milk to espresso varies, but it's typically 1:1 or 1:2 milk to espresso. Unlike a latte, a cortado has very little or no foamed milk. The milk is steamed but not heavily textured, and the drink is meant to balance the strength of the Espresso with the milk's sweetness and texture. It's commonly served in a small glass, and has origins in Spain.
