The origins of the name "Boxcar" cocktail are murky. Before Prohibition, bartenders in 18th and 19th century America were known to serve drinks in boxes for their customers. A boxcar cocktail could be served in a small box or served in a tall glass with ice cubes.
Boxcar cocktails are easy to make but they taste great too! When they’re made with whiskey and gin, they taste like an Old Fashioned when served sans sugar and bitters. With a mix of whiskey and gin, this drink is easy to make and tastes great.
A popular variation is the Red Eye: swap coffee liqueur for the whiskey. You can also add lemon juice and Grenadine syrup for a tasty twist on the traditional Boxcar cocktail recipe.
