Burger King is Testing a Vegetarian Whopper Made With Impossible Burger

Burger King is testing a vegetarian version of its Whopper that uses an Impossible Burger for its patties, becoming the first national fast-food chain to sell the plant-based burger. From a report: The Restaurant Brands International subsidiary is offering the Impossible Whopper at 59 St. Louis locations. The chain already sells veggie patties made by Kellogg’s vegetarian brand, Morningstar Farms. To announce the launch, Burger King released a video on April Fools’ Day that shows unsuspecting Whopper fans eating the version with the Impossible Burger and then exclaiming that they can’t taste the difference. Silicon Valley-based Impossible Foods genetically engineers heme, a protein that makes the vegetarian-friendly burger taste like meat. The ingredient is also responsible for giving the patty red juices that make it look like it’s bleeding, just like a piece of beef.
