I put together a drink to work with ginger liqueur, and have been playing around with the base spirit. First time around, I used brandy, which was good. Last time, bourbon, which was also good. This time, Rye, which is good as well.
1.5 measure base spirit.
.5 measure Dry Vermouth
.5 measure Ginger Liqueur
.5 measure Lemon Juice
bitters, whatever type you feel like.
Very New Orleansy formula (proportions inspired by the various crustas), so I think I'll probably stick with brandy/bourbon/rye on this one, and come up with something different for gin and rum.
