I'd call it a 4.25 at best. The pear and celery pair well together. But be careful not to be heavy handed with the bitters. I'm definitely going to play with this. Seems like it has room to grow. Maybe a little capsicum heat?
Had to make my own version of this using Pear Liqueur and 1/12 Ancho Reyes Liqueur.
Swapped the Celery for Bobs Coriander bitters.
Definitely on a return a very drinkable Gin Sour.
Benefited from just the dash of absinthe - hardly worth the extra glass for the discard but I NEVER throw out absinthe.
