Two startups, Impossible Burger and Beyond Burger, have created veggie patties that are dead ringers for beef—they even bleed. (Beyond Meat pulls this off using beets, while Impossible Foods uses a yeast-based version of “heme,” the stuff that gives beef its meaty flavor.) How do they taste? “Pretty darn good!” according to some committed carnivores in our office. Find the Beyond Meat burger at Whole Foods, and the Impossible Burger at restaurants in NYC, LA and other cities.
