Overview:In the first episode, Heston turned his attention to Chicken tikka masala. The search started at his local curry house in Cookham, Berkshire, but soon took him to Delhi where he tried to unravel the complicated roots of this dish. On returning to his restaurant in Bray, Heston tried to build his own tandoor but soon realised that most people aren't able to dig a five-foot-deep hole in the ground and line it with fire bricks. So, he came up with a more accessible solution - a barbecue, but with a few bespoke alterations. In Cambridge, Heston put a chicken breast through a magnetic resonance imaging (MRI) scan to see how a marinade affects the meat as he tried to create the perfect sauce.
