JAKARTA - Britain's Prince William has surprised shoppers by serving eco-friendly burgers from a food truck in London.

In a video released on Sunday, the heir to the throne shares the "Earthshot Burger", a reference to the work of last year's Earthshot Prize winners, which he founded to help develop solutions to environmental problems.

"Coming soon," said the prince as he served burgers to stunned customers.

"Good morning everyone, it's cooked, ready to be enjoyed," he said, citing Reuters, July 31

The goal of Prince William, who works closely with the founders of the Sorted Food YouTube channel that reviews kitchen gadgets and shares recipes, is to raise the profile and work of three previous Earthshot prize winners.

"So this box that you're about to eat is made by a company called Notpla and instead of using plastic, they make a layer of seaweed," the prince told customers in the burger van.

"The ingredients in this burger are grown in greenhouses in India from a company called Kheyti, and last but not least, the cooking method uses a device called Mukuru Clean Stoves, designed by a woman in Kenya who came up with this concept to reduce air pollution. ," said Prince William.

"Can't guarantee the taste, the quality, but... I really like it," he said.

Meanwhile, one of the visitors said he saw the future king.

"It takes my brain three seconds to work it out. Am I dreaming? Am I getting enough sleep?" said a visitor as quoted from The Sun.

The chefs created this spicy potato-based burger flavored with garlic, ginger and chili peppers - with pickled vegetables served on a bun.
