My problem is after a lifetime of Marmite abuse and a couple of decades of smoking my palette is not what it should be and I find vodka a very difficult spirit in cocktails as it adds nothing... unlike Gin which brings all sorts of flavours or Rum which has a complexity of it's own. Maybe I will try this recipe with Gin, or, I wonder, if we were to add something like Gren Chartreuse or Absinthe or Falurnam in small doses or Grand Marnier or Benedictine or something just to add layers in there
