It was a rainy weekend and I had a hankering for something with port in it so went on a hunt through the library (aka the 3 foot of shelf space I'm allowed to indulge my cocktail book habit on) for something to sate my thirst. A few 'experiments', a packet of crackers and several hunks of cheese later (an intrepid cocktail hunter sometimes needs sustenance) I'd found the Betsy Ross.
Originally named in honour of the woman that sewed the first American flag, the drink surfaced in a 1940's cocktail book and with equal parts brandy and port its makes a great after dinner drink. Don't worry too much about the type of port, as long as it's a ruby one it will be perfect and curaçao and Cointreau are essentially the same thing so use what you have to hand.
