Jimmy's Food Factory is back to unravel the secrets of supermarket food. Farmer Jimmy Doherty sets up his own food factory in a barn. Using farmyard and household junk, he is creating his own supermarket production line to find out what they are really doing to our food.

Jimmy looks at how food factories use extreme temperatures to create our everyday foods. By turning down the temperature, Jimmy makes soft-serve ice-cream and uncovers something unexpected about the ice-cream van favourite.

Using heat and a high-pressure crusher, he makes one of the weirdest snacks around - prawn crackers. And he finds that it takes a lot of effort to make what the food takeaways give away for free.

Jimmy likes his curry spicy hot, and he discovers just how hot it has to be to last for two years in our cupboards. And he meets a broccoli farmer to see why he's in such a hurry to cool off. Show less
