Gregg Wallace explores the Nottinghamshire factory that produces 250,000 jars of curry sauce each day. Gregg is making a supersized 3,000-kilo batch of tikka masala - enough to feed 25,000 people. He loads in almost half a tonne of yoghurt and cream and ten other ingredients, including 30 kilos - or 10,000 cloves - of garlic. He deploys an unusual kitchen implement - a hosepipe - to get his ingredients into the cooking pot and heats it for 30 minutes. Then he checks it for colour against a decorating colour chart. Finally his jars head into a pasteuriser for a second two-hour cooking session.
