I recently touted my new addiction to iced coffee on Facebook. I was pointed in the direction of this iced coffee concentrate. I wasn't familiar with this method of making iced coffee so I gave it a try. It was good, but to be honest, it wasn't any better than my usual, less time consuming method. We always have leftover coffee from our morning brew and that's perfect for this since it's had all day to sit and cool. If you don't have cool coffee available, you can use instant. I tried it with Starbucks Via and it was tasty. Whatever you do, just please don't try to make iced coffee with hot coffee. You will end up with a weak, watered down wannabe. I like to use a jar with a tight fitting lid so I can shake all the ingredients together to get it icy cold and extra creamy. I just fill my jar about half way up with ice then add coffee to fill the jar about 3/4 of the way up. I splash in heavy cream, you can use milk if you want to, but I'm telling you, the cream is where it's at. You really only need a tiny bit so it's not as sinful as it sounds. I sweeten with vanilla stevia drops, but use your sweetener of choice. I put the lid on my jar and shake, shake, shake it. There really is something to that shaken, not stirred, thing.
