UK appliance brand Kenwood just launched in the United States with the splashy debut of a hot new appliance, the Cooking Chef ($2,000). The multipurpose machine is a blender, food processor, grater, juicer, meat grinder, and more, all in one unit. What's more, it has induction heating, which allows home cooks to sous vide, smoke, sauté, stir-fry . . . the list goes on. The only thing it doesn't include is an oven.
