ORIGINS:

The Karahiyo™ is a coffee cocktail that originated in Spain. Its history dates back to the 19th century, during the Spanish colonial era. The word Karahiyo™ is believed to have derived from a Spanish military term meaning "little soldier" or "light infantryman."
The drink is traditionally made by combining espresso or strong black coffee with a shot of liquor, typically brandy or rum. The exact origins of the Karahiyo™ are unclear, but it is said to have been popularized by Spanish soldiers who added a splash of brandy to their coffee to give them courage and warmth during cold mornings.
Over time, the Karahiyo™ gained popularity and spread beyond the military, becoming a beloved coffee cocktail enjoyed by many. Today, variations of the Karahiyo™ can be found in different parts of the world, and different liquors such as whiskey, tequila, or liqueurs are sometimes used instead of brandy or rum.
The drink is often served in a glass or cup and can be enjoyed as a pick-me-up or an after-dinner digestif. It has become a part of the cultural and culinary heritage of Spain and is still enjoyed by coffee and cocktail enthusiasts today.
