We kick off this week’s show at Crossroads Kitchen, an upscale plant-based restaurant in West Hollywood, to taste the Impossible Burger. It’s the latest beef poseur to make its way onto the menus of a handful of restaurants across Southern California. After hearing all the praise this vegan patty has garnered from so many people — David Chang in New York is a fan, and Chris Cosentino in San Francisco made “beef” tartare from the stuff — we just had to try it. The Impossible Burger is supposed to mimic the mouthfeel and visual cues of meat, like bleeding. Executive chef Scot Jones explains how it’s served at Crossroads, and UCLA professors Amy Rowat and Jenny Jay break down the science of how the burger is made.
