Similar enough to a Pencillin, but just lacks edge. I would consider at least cutting up some slices of ginger and muddle them into the tin before shaking. Maybe a small pinch of black pepper as well... Now my mind is trailing off thinking of subtle accents, hmm...

Didn't try the cocktail yet, but this is a cold version of the Hot Toddy recipe I give my dad when he's ill, even down to the split base of honey and ginger syrup.
