Food Factory (2012)

Season 2: Episode 20

Discover how humble rice and sugar are transformed into a gooey, crunchy marshmallow bar topped with rainbow-coloured chocolate chips; the root, stem and flowery part of a Japanese plant are pureed into a delicate but very spicy sidekick to sushi; meatless deli magicians, Tofurky, turn soy milk into mouthwateringly aromatic Italian veggie sausages; and, how many microscopic layers are baked into the flaky dough of a sinfully moist and tender Mini Choco bun.
