Renewed my acquaintance with this drink this weekend and the diet is out of the window and I will chastise myself on Monday. I have added a couple of dashes of orange bitters too "orange out". I also have Fentimans Valencian orange tonic. Will try with this to see if the drink becomes too bitter. I do not have too sweet a tooth so this may work. Will report back on my findings. If this works could it be a Flucky Duff?
