How to make the Prince of Wales’s Earthshot burger

The Prince of Wales and The Earthshot Prize have collaborated with Sorted Food on a new veggie burger.

The Prince of Wales has teamed up with popular YouTube channel, Sorted Food, to create the first Earthshot Burger.

The veggie burger was created with Earthshot Prize-winning products, and a video posted on YouTube shows William handing out meals from a food van in central London with the Sorted Food chefs.

The burger, filled with vegetables, spices, pickles and finished with a minty vegan mayonnaise, was developed by the sustainable packaging start-up Notpla (winner of the Build A Waste-Free World category), environmentally-friendly stove company Mukuru Clean Stoves (winner of the Clean Our Air category), and Kheyti’s Greenhouse-in-a-box, winner of the Protect and Restore Nature category.

The collaboration is part of The Earthshot Prize’s new partnership with YouTube, to encourage users to create more content around climate change.

Here’s how you can make your own at home…

6. Tip in the spices and stir to combine.

7. Tip in the sliced pepper and continue to cook for five minutes until the pepper softens and releases its liquid.
