Solid addition to a martini repertoire. I made for two, scaling proportions at 1.5 which went over well. Next time will just do a very light rinse or mist with the absinthe so as not to overpower the creme de violette. A dash of orange bitters also works.
I agree - the absinthe is a touch too powerful. I would reduce it a smidge (technical term) and slightly increase the crème de violette.
