In this first 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 preserves, pickles and spreads battling it out for one place in the final. Sara makes apple and chilli jelly from her back garden in a west London street, using home-grown apples. But when she brings it to Yorkshire, will the locals like what they taste? Louise from Brighton has a much-loved family recipe for Filipino papaya pickle. Having given up her career as a lawyer, she hopes the Yorkshire customers can stand the heat and prove she has got a future in food. Couple Linzi and Jason from Dorset have lost ten stone between them, largely down to changing their diet and eating more protein in the shape of peanut butter. Now they make and sell their own, but will they be business savvy enough to make a success of it? Finally, retired florist Pam and her daughter Emily make runner bean chutney from homegrown veg from their garden in Herefordshire. However, whether they can make a virtue of their family-run business and charm the shoppers remains to be seen.
