The Tom Collins is probably the most recognizable highball style cocktail. Another classic highball is the El Diablo. The Black Donald is essentially an El Diablo using Scotch in place of Tequila and Drambuie in place of Creme de Cassis. Grab your nearest bottle of single malt and give it a go!
3/4 oz Drambuie
3/4 oz lime juice
shake first three ingredients with ice
strain into an ice filled collins glass
top with ginger beer
garnish with a lime wheel
