Burger King tests Whopper made with Impossible Burger

Study Finds Burger King to Be America's Fastest Drive-Thru Chain According to a 'QSR Magazine' study, it typically takes three minutes and 13 seconds fully complete orders. Following BK in speed was Dunkin in second and Wendy’s in third. Although the burger joint is the fastest to complete orders, it's not the top-selling fast food chain. McDonald’s and Chick-fil-A are the two top-selling chains but are the two slowest. Every drive-thru in the study got food to the customer in under 5 minutes.

Atlanta vegetarians can get an Impossible Burger at nearly a dozen locations, but they have to get out of their cars to do so.

That might change soon.

Burger King is testing a vegetarian Whopper made with the “veggie burger that bleeds,” as the Impossible patty is often called.

The plant-based vegan patty — made of water, plant proteins, coconut oil and heme, a natural molecule that gives burgers their distinctive taste and is found in plants — is designed to look and taste like a traditional red meat burger, The AJC reported in 2017. California-based Impossible Foods has gotten more than $250 million in financial backing from Bill Gates, venture fund Temasek and several other businesses.

"We wanted to make sure we had something that lived up to the expectations of the Whopper," Burger King's North America president, Christopher Finazzo, told Reuters. "We've done sort of a blind taste test with our franchisees, with people in the office, with my partners on the executive team, and virtually nobody can tell the difference."

Impossible Foods’ CFO, David Lee, announced the joint venture on Twitter.

Impossible Foods tailored a patty specifically for the Whopper, chief executive Pat Brown told Reuters.

Burger King is the first national fast-food chain to offer the Impossible Burger, but currently sells it only in 59 St. Louis locations.

The Impossible Whopper will cost about a dollar more than a beef Whopper, CNBC reported, adding that Finazzo said research found that customers don't mind paying more and like the plant-based burger for its health benefits.

If you don't mind getting out of your car and eating in a restaurant, you can already try the Impossible Burger here in Atlanta at one of 11 places.
