Sometimes a pot of coffee isn’t enough. Problem is, coffee drinkers don’t really know that until they have hit the last drop. At that point a jittery conundrum reveals itself: make another pot or just do without? (Or run to the corner cafe.) Easing the decision-making process is the One Cup Microwave Coffee Maker. Just add ground coffee, drop it in a cup of water and nuke it. Soon enough that extra cup of coffee will emerge hot and steaming — and thanks to its small size it easily washes out for the next extra cup of coffee.
