S5 E1 • Potato Waffles
Gregg Wallace is in Lowestoft, at an enormous factory where they produce 450 tonnes of frozen food each day. He follows the production of frozen potato waffles, from the arrival of 25 tonnes of potatoes right through to dispatch. Along the way he discovers how they make a monster amount of mash and marvels at the technology which stamps out a million identical waffles every 24 hours, each weighing 68 grams and exactly 15 mm thick. Meanwhile Cherry Healey is learning about the differences between waxy and floury potatoes and finding out which spud you should use for which job. Small waxy potatoes are best in salads and boiled, while floury potatoes produce the best mash and roasties. She’s also asking whether, in these carb-conscious days, we’re unfairly demonising the potato. At King’s College London she meets a dietician who runs tests which show that the potato, gram for gram, has more vitamin C than beetroot and carrot and more potassium than banana. Keeping hold of these nutrients isn’t easy. But Cherry is delighted to discover that skin-on wedges, as long as you go easy on the oil, are a nutritional winner. Historian Ruth Goodman is myth busting Walter Raleigh’s connection to potatoes. She discovers that he couldn’t have brought them back from North America, because there weren’t potatoes there until 20 years after he died. Instead the credit must go to Spanish explorers and an enterprising French chemist called Parmentier, who popularised this exotic new vegetable. She also meets one of the inventors of the potato waffle, who shows her how Mr Whippy ice creams were the inspiration behind this teatime treat.

And Ruth Goodman is investigating the technology that allows frozen foods like pizza to be transported across the globe.

S5 E5 • Cheese
Gregg Wallace is in Gateshead at a cheese factory where they produce 3,000 tonnes of spreadable cheese every year. He follows the production of jalapeno chilli flavour cheese from a 28,000 litre delivery of milk to 5,400 squeezy tubes. The process begins in a traditional way – by making cheddar. He learns about the microbiology responsible for splitting milk into curds and whey and forming this hard cheese. He then chops 344 kilos of cheddar and gouda to make the base for his squeezy cheese, and puts it in a huge blender with whey, water and other ingredients in order to stabilise it and keep it soft and spreadable. Meanwhile, Cherry Healey is finding out how bacteria are responsible for the huge variety in smell, taste and appearance of different types of cheese. She learns that some smelly cheeses contain the same bacteria that are responsible for stinky feet. In cheese the odour is a by-product, a sign that the bacteria are silently changing the internal texture and taste of the product. She also learns the scientific rules for making perfect cheese on toast. It is all about medium sliced white bread, with precisely 50g of grated medium cheddar, set an exact 18 centimetres from the grill. Historian Ruth Goodman is finding out how cheddar, originally just one of hundreds of regional varieties in the UK, became the predominant hard cheese world wide. She discovers that it is down to a Victorian cheesemaker called Joseph Harding who first standardised production methods. She also makes a batch of processed cheese, using Kraft’s original 100-year-old patent recipe.
