In this fourth heat, four food producers with fledgling businesses come to test out their products on the locals in Malhamdale, in the heart of the Yorkshire Dales. They have two days in the shop to promote and sell their wares.

This time it is makers of cooking sauces competing against each other for a place in the final. Joe is a teacher from Runcorn who spices things up with his homemade hot sauce. However, with such a niche product, can he persuade enough of the Yorkshire locals to give his sauce a try and prove he's got a viable business?

Spanish-born Beatriz makes and sells a taste from home with her 'paella in a bottle'. But the judges find her labels confusing, so only time will tell whether her sales skills can outweigh the branding issues.

Alice makes salted caramel sauce in her country kitchen in Northern Ireland. She prides herself on only using ingredients local to her, but will her brand travel to Yorkshire?

Finally, Kiran from Solihull has given up a successful career to concentrate on making and selling her healthy take on curry sauce. However, she needs to make the most of her brand message if she's going to succeed.

Tom Kerridge meets members of the community as they try the range of sauces. Meanwhile, judges Alison Swan Parente and Nisha Katona visit the food producers at home to see how well their product is made and decide how well they promote and sell their item to the Yorkshire locals in the shop. The winner is the fledgling business that is most viable and most deserving of the title best up-and-coming artisan. Show less
