The “human-flavored” vegan burger won a prize at the Cannes Film Festival.

How producers identified the taste of human meat is not specified.

The burger “with the taste of human meat” was awarded two awards - “Silver Brand Experience” and “Golden Lion” at the festival “Cannes Lions”.

The authors of the controversial experiment are the Swedish food company Oumph!

The burger is made from soy, mushrooms and wheat protein, as well as vegetable fats and a “mysterious spice mixture.”
