I thought a "Black Cow" was a root beer float made with chocolate ice cream, rather than vanilla? But then, I didn't search the interwebs to find out.
On a different part of today's celebrations, I'm not a huge fan of regular iced tea. Does it still count if I make a cocktail with Swedish Punsch? Swedish Punsch, for those who don't know, is a cocktail ingredient that uses a rum variant called Batavia-Arrack from Indonesia, combined with citrus, spices, and, most notably for present purposes, tea. It was popular in the early part of the 20th century, and I make it myself (although I think you can occasionally find some pre-bottled out there - try that interwebs thing). It makes a delicious summer drink served with tonic, white Port, and lime juice over ice. Technically that means it's got iced-tea in it, right?
