Mukka Express is the ingenious novelty created by Bialetti -- with a personality all its own! And it's as easy to use as a coffee maker. Simply fill the lower chamber with water and the filter with your favorite dark roast or espresso. Then open the lid and fill with milk to the level indicated. Place the pot on your stovetop until the water boils. Within four minutes you'll be enjoying fresh cappuccino, just like the ones at your favorite coffee bar.
