Most kitchen gadgets are shoved in a cabinet as soon as they've done their job. The Alessi Ossidiana Stovetop Espresso Maker us meant to stay in view. Designed by Mario Trimarchi, it's named after the volcanic stone obsidian, and features an interesting, dented form, made from cast aluminum. The black handle and knob are made from thermoplastic resin, and serve to contrast with the silver body. Available in 1, 3, or 6 cup capacities.
