I still have about 25 ml left of D.R. Harris's Pick-me-up that I acquired in London a few years back. I hadn't thought of it in a long time, but it lists a fair representation of bitter ingredients (gentian tincture, oil of cloves, cardamom tincture). I was wondering whether anyone had ever considered it as a bittering flavor in a cocktail preparation? After all, "pick-me-up" isn't that far from "corpse reviver", is it?
