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. In the first programme Jimmy makes some pub grub classics. Using a high-powered spud gun, Jimmy gets explosive results when he tries to make oven chips. Creating chicken kievs proves messy when he makes a home-made meat processing machine from an old car tyre. To complete his pub menu Jimmy discovers how a farm boss, who produces 480,000 sirloin steaks every year, makes sure every steak is tender and juicy. And Jimmy turns detective to find out how they stop imposters ending up in our packets of peanuts.
