Sous vide is the next big thing in cooking — but unfortunately, you've had to shell out a ton of cash if you wanted to bring the technology home. The Nomiku ($300) is poised to do so at a much lower price and without the need for a large, dedicated machine. It sits down in a standard pot, heating the water to whatever temperature you set -- using the dial control and 1.3-inch OLED screen -- and keeping it there for as long as you need. The result? Perfectly cooked meals, every time, with less fuss than you'd expect.
