Jimmy Doherty on the trail of an exotic spice on tonight's TV

JIMMY DOHERTY is investigating turmeric – sometimes called Indian saffron or the golden spice. With a warm, bitter taste, it is used to flavour or colour curry powders, mustards, butters, dressings and cheeses. But not only does it add spice to food, turmeric can also play an important role in digesting food and is used widely to make medicine. Jimmy visits India on the trail of the exotic spice and finds himself at a wedding where guests are showered with it. Also tonight, Kate Quilton wants to find out how much milk goes into a bar of chocolate, and if you have ever wondered why popular vegetable asparagus gives some of us a rotten-like pungent problem with our pee, Andi Oliver may have the answer.

Churchill: Fallen Hero

Churchill: Fallen Hero (C5, 9pm)

The series reaches 1945 and Winston Churchill has led Britain to victory in the Second World War. He’s determined to carry on as Prime Minister and calls a General Election, fully expecting voters to give him another five years in No 10. But he’s in for a shock. While Nazi Germany has surrendered and, for many, Churchill is a walking symbol of victory, the tide begins to turn and the PM struggles on the campaign trail. The ageing leader represents the past and Britain is now looking to its future. In extraordinary and moving scenes, the great war hero’s speeches are met with boos rather than cheers.
