Sheila Dillon charts the rise of the humble mac'n'cheese: a dish that crosses culture and classes and has established itself as a popular comfort food across the world.

We discover the history of the dish. Food historian Polly Russell tells us how a macaroni recipe first appeared in the UK in the 1700s and slowly it became more and more prevalent over the subsequent centuries.

We'll hear how macaroni cheese became a staple in the UK: cheap and easy to make its popularity spread. It was also embraced by Caribbean cuisine, regularly eaten as a side dish, especially with Sunday lunch, and now there's even an annual celebration of the meal. Each May Glasgow hosts 'Pastaval' - a festival of Mac n Cheese. The event sells-out each year and is popular with everyone.

And whilst you can still buy basic packet versions, tinned macaroni cheese and simple home-made macaroni cheese is easy to make, there are many 'going-to-town' on the dish: Lobster mac n cheese anyone?

This is the story of a dish that crosses cultures and classes to be the world's favourite comfort food.
