If you treat Scotch like a religion, try this simple and classic cocktail. Be sure to use a spicy ginger ale so you get the most out of the three-part combo. Not a fan of Scotch? The Presbyterian is also delicious with a measure of bourbon.
Our introduction to the Scotch Presbyterian involved half soda, half water (think of the polite baptismal). And we understood the Bourbon version as half soda and half ginger ale. (Then too, we have a long practice of spirits that taught us only to sweeten Scotch with Drambuie.)
