Sometimes a pot of coffee isnâ€™t enough. Problem is, coffee drinkers donâ€™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 cafÃ©.) 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 steamingâ€”and thanks to its small size it easily washes out for the next extra cup of coffee.
