Looking for a gift idea for someone who loves bar-tending but already has great glassware and a bar tools set.
Cool cocktail picks for spearing said artisinal olives and cherries. I have some that are glass, and look like an olive (green, replete with a red pimento inside) fused to the top of a clear spear. I have others that are plastic, and look like miniature Martini glasses perched on top of a clear plastic spear, again, there's a teeeeeeny-tiny olive, spear and pimento in the little glass. Way cool.
Cool swizzle sticks (those are easy to find, look at Cost Plus/World Market or Pier One) for mixing things like Cuba Libres or Gin and Tonics.
Cool tonic waters like Fever Tree or Q Tonic. Way better than what you can get in the megamarts.
Cool liqueurs like Luxardo Maraschino, Cynar, Creme de Violette, Campari, Benadictine, St. Germaine, Pernod and so on.
The possibilities are endless. If you have time, look at some cocktalian forums. Just Google "Drinkboy", "Cocktail Database" "eGullet" (once there, search for cocktails) and "Esquire Drinks". They will give you limitless options.
