Well-balanced, with zesty lemon and absinthe just shining through. I've added the merest dash of sugar, but depending on your personal tastes, citrus juice...
I tried this with a green tea infused Bombay sapphire last night and was very pleased with the added floral notes from the tea. It might be my standard house variant for this cocktail.
As always I enjoyed the history article by Simon Difford. This is one of my favourite cocktails. I like absinthe, but you have to control the glass “wash” carefully.
