Earlier this year, the food scientists at Impossible Foods came up with a recipe for a meatless burger patty using wheat, potato, and soy protein. The difference between this and most other vegan patties is the inclusion of coconut oil, to help replicate the texture of beef, and a compound called heme, to replicate blood. The result is a patty that looks and “bleeds” like beef. But does it taste like beef? Onion Inc. creative director Leonardo Garcia went to Umami Burger in Los Angeles to give the Impossible Burger a try.
