Coffee ice. This is one of those brilliant things that seems so simple after you've heard of it. It took me a while to hear of it, but now I'm on board. I've been trying to make a batch of cold brewed coffee every night, and now I plan to add this to the routine. That way when I pour myself a nice iced coffee in the warmer days to come, I won't be left with a watered down beverage. So simple, right?
