Barraquito

Barraquito is a coffee liqueur commonly available on Tenerife (one of the Canary Islands), also known as zaperoco. Amongst the population of Santa Cruz de Tenerife, it is said that barraquito appeared in the mid-20th century. Its name refers to a frequent client of Bar Imperial, Don Sebastián Rubio, nicknamed "Barraco" or "Barraquito", who always asked for a cortado with condensed milk, a shot of Licor 43, a lemon rind, and cinnamon in a long glass. This bar is still active and is located in Santa Cruz de Tenerife. The barraquito is a multi-layered coffee liqueur drink (though non-liqueur versions are available) normally served in a glass to enable easy viewing of the different layers.
