What could be more typical in Spain, to start the day, than friends & café con leche? It is often served hot in a glass (not a mug). Coffee with milk, half and half doses. And believe you me, mine is always ordered with MORE milk, which is called a "manchado" (= "stained"). And on the other side of café con leche is coffee with just a touch of milk (they order a "cortado" meaning "cut"). Or you can drink full-blown espresso, black (be my guest!).
Inga & Yasmin & I recently had morning coffee with a good friend José María, & his high school buddy Germán (on left).
