pulp

It starts with a pile of soy pulp, which is wrapped in banana leaves and sprinkled with the spores of a fungus called Neurospora intermedia.

Food counterfeiting also happens in the US – in some cases, cheap and even dangerous ingredients are being used to produce “fake” versions of expensive cheese, such as parmesan made using additives derived from wood pulp.

Another method, recorded in 1735, was to scoop out the pulp, mix it with chopped apples and sugar, bake this in the hollowed pumpkin, then eat it spread on bread.

"Berger’s film is adapted, quite faithfully, from Robert Harris’s 2016 novel," noted Vulture's Bilge Ebiri, "and it combines the pulp velocity of a great airport read with the gravitas of high drama."

The mixture is then left to ferment for several weeks, transforming the banana pulp into a potent, aromatic wine, containing 13% alcohol - similar to wine made from grapes.
