I got these given to me for Christmas from the wifey and thought WTF? I drink my Whiskey on the Rocks but Ice, I like melted ice.. then I had a great idea? Ever had that moment when you ve let your absinthe sit for a while and it goes warm? Welll just stick these in for a few minutes, extract and voila you have your cold drink back!
