Induction cooking is great for budding chefs: it rarely needs preheating, it's energy-efficient and it's safer than conventional burners. Getting it has usually meant going for a full-size oven or a cooktop, however, which isn't always practical if you're in an apartment or otherwise can't justify tearing out your existing appliances. That's where Panasonic thinks it can help. It just introduced the first-ever countertop induction oven, giving you all the benefits of the technology in a relatively tiny, enclosed space. If you want to grill a barbecue-grade steak, you can do it with a device that's roughly the size of your microwave.
