A barraquito is something between coffee and dessert.
It takes a while to prepare one, and there are lots of variations. This is how the kiosk in San José makes them.
First, a good layer of condensed milk followed by a sizable glug or “43” liqueur or brandy. Then coffee from the expresso machine followed by hot milk, and froth. Finally, the barraquito is topped off with a sprinkle of cinnamon, two coffee beans, and a sliver of lemon peel.
Delicious!
