Canchánchara is a classic Cuban cocktail, and one of the oldest on record. It dates back to at least the Ten Years’ War of the 19th century, taken warm as a healing concoction by Cuban guerrillas fighting against Spain for independence. It might go back even further, bearing a resemblance to a drink long enjoyed by the native Taino people.
Traditionally, Cancháncharas are sipped from simple clay mugs, which helps to keep them well-chilled. Of course, you can use a glass – but there is something to be said for the experience of drinking one from unglazed clay, ice-cold and beaded with condensation.
Shake everything (except the sparkling water) with ice, and strain into an ice-filled short glass or clay mug. Top with a splash of sparkling water to taste, and garnish with a lime wedge or wheel.
