Behind the scenes as Aldi bids to become the nation's number one festive supermarket. But will a collapsing panna cotta and a hitch with the Yorkshire puddings put a dent in their plans?

In the final week in the tasting room, supermarket buyer Julie Ashfield is looking for her chain's next big thing in the `treat" category. Among the wild and the wacky produce, are some hand-made chocolates that will definitely tug at the heartstrings, beer-filled Yorkshire puddings and a bar of chocolate packed with crisps vying for a coveted place on the shelves.

Products including Norfolk mustard ice-cream and chocolate-flavoured pasta bid to make their way onto the shelves at Aldi. Flavour is the watch word, as the suppliers do their best to convince the retailer's representative Julie that their product can compete with the iconic brands that customers all know and love.

Cameras look on as small-scale fresh and deli specialist producers get the rare opportunity to pitch their products to bosses of the major supermarket. The food suppliers pitching to Aldi's head of buying include the captain of GB's Butchery Olympics team, two loved-up hipsters hawking vegan cheese and an all-singing, all-dancing Indian snack obsessive who wants to make Melton Mowbray famous for samosas.

Aldi's head buyer Julie goes on the hunt for the next healthy and wholesome product. From camel's milk to kombucha, roast dinner kimchi and protein-packed fava beans, Julie's tastebuds are put to the test. After a site visit by Chris Bavin and Anita Rani to find out if they're really ready to scale and supply to almost 1,000 Aldi stores, one lucky supplier is selected and lands a contract that will change their business forever.

The nationwide search for new products to be stocked on Aldi's shelves continues with the bakery category. Participants include a chef from Florida who's patented his own dessert sushi, a pair of ambitious young donut connoisseurs, a patisserie perfectionist who has given her Parisian pastries an Indian twist, and an engaged couple whose fruit cakes pack a serious rum punch.
