Electric pressure cookers hit it big in American home kitchens a few years back because, along with the perceived lower risk of dinner on the ceiling, they cook food fast. Something like beef stew, which takes all day in a slow cooker, needs as little as 25 minutes under pressure. With an extra hit of power, Instant Pot's new six-quart Max promises to take that speed and turn it up to 11, getting dinner to the table even faster. Could it? I wondered.
