The Basque Mule is a refreshing cocktail that combines the flavors of the Basque region with the classic Moscow Mule. Made with local Basque cider, ginger beer, lime juice, and a splash of vodka, this cocktail is the perfect balance of sweet, tart, and spicy. Served over ice and garnished with a slice of lime and a sprig of mint, the Basque Mule is a must-try cocktail in San Sebastian.
