Celebrating my 21st wedding anniversary with Ms. Cocktail Den is a great reason to look for a themed drink. I discovered the Blackjack, which naturally made me think of the card game, in which 21 is a winning hand. This version of the Blackjack comes from Steve the Bartender in Australia.
Combine in a mixing glass with ice, stir with the confidence that comes when you see you have a jack and the ace of spades, and strain into a chilled glass. Orange peel and/or amarena cherry garnish optional.
The Blackjack is dark and delicious. Brandy, your first cocktail "card," brings a solid foundation. Even though it's all torched Dutch grapes, all cognac is brandy, but not all brandy is cognac (a key part of my 24601). As in a Royal Blood, a hint of Cherry Heering goes a long way. Mr. Black is from Australia, and it's very good. We had to acquire it via the Internet. Kahlua could be a substitute, but it doesn't have the same depth, so the resulting Blackjack will be a little different. Do you want to stack the deck, libationally (I made up this word) speaking? Add some coffee or molé bitters, just as you would in a 43 Up or Left Hand.
A word of caution -- have too many Blackjacks, and you might end up with the Charlie Sheen version of "winning!" (Google it). So do you have a winning cocktail hand?
