I'm not religious, except about whiskey, so the Presbyterian's a no-brainer. It's easy drinking, just some Scotch with some club soda and ginger ale added. We like to dress up the glass with a little candied ginger.
Not a Scotch fan? Bourbon or rye will do just as well and won't have the smokiness.
Since we (read: Willy) are big Scotch drinkers over here...we've got ours in a larger version of our hand engraved liquor decanters.
2 oz Scotch
1 lemon twist
Fill a highball glass with ice. Add scotch, and fill with equal parts club soda and ginger ale. Stack candied ginger with lemon twist on cocktail pick for garnish.
