This drink is named for the golfer Arnold Palmer, and if we're to believe the story on the Arnold Palmer Tee website, invented by him too. Apparently the properties fresh-squeezed lemonade combined with the caffeine of black iced tea provide a uniquely refreshing beverage experience. Especially when one is coming in from a long day on the golf course.
And I'd have to agree! I can't speak to post-golf dehydration, but as a remedy for post-work-out or even just post-work dehydration, it's excellent. I also happen to know that a glass goes quite well with a plate of fried chicken.
The drink is non-alcoholic in nature, but that doesn't mean that we can't take a few liberties. A shot of gin or vodka would be right at home here. I could even see using a bit of limoncello and a tea-infused simple syrup to make a fancy Arnold Palmer martini.
