1 1/2 ounces light blended Scotch whiskey
1 ounce Tang (2 tablespoons in 1 cup water to make it) or 1 ounce freshly squeezed orange juice
1/2 ounce Amaretto
1 dash Angostura bitters
Orange peel, expressed through a flame (optional, but it adds more depth of flavor)
Shake the Scotch, Tang, Amaretto, and bitters with ice for 15 seconds and strain into a chilled rocks glass (with large ice cube) or a chilled coupe. Express orange peel through the flame of a lit match over the drinks and drop peel into glass.
