The Carajillo is a traditional Spanish drink combining coffee with a spirit — the name likely derives from 'coraje' (courage), echoing the colonial-era tradition of soldiers fortifying their coffee with rum. In Spain it is classically made with brandy or rum. The Licor 43 version exploded in Mexico around 2015, largely through brand promotion, and is now one of the most ordered cocktails in Mexican bars and restaurants.
