In this episode, Jimmy tries out some of the technological tricks the food factories use to make food that's quick and easy to prepare. Turning a fire extinguisher into a squirty cream canister, Jimmy squeezes out the secrets of the cream you don't need to whip. A mangle and an office shredder come in handy when he tries to work out what makes instant noodles 'instant', and in a microwave-rice factory, Jimmy discovers how they can guarantee their pre-cooked rice is safe to eat. He also joins a lettuce grower to see how technology protects his fragile crop from the extremes of the British weather.
