Jimmy's in Kenya, looking into what makes one tea more expensive than another. At a visit to one of the country's largest tea plantations, Jimmy discovers that tea comes in multiple grades and flavours, and every batch can be subtly different. So how come the big teabag manufacturers are able to produce a brew that tastes the same each time? To find out, Jimmy is invited into the inner sanctum of one of the UK's largest tea producers, where he meets a man whose taste buds are insured for one million pounds.
Kate keeps seeing rosemary listed as an unlikely ingredient in hundreds of different products, ranging from chocolate chip cookies to ice cream… but none of these foods have even the slightest hint of rosemary flavour. Why not? To unravel this mystery, Kate heads to Slovenia, then Northern Ireland, where she discovers that the rosemary nothing to do with flavouring and actually has an altogether different use…
And Matt's in Cornwall, diving for the edible seaweed that has started cropping up on our supermarket shelves. Can we eat any old seaweed? And how will seaweed spaghetti match up in a blind taste test against good old-fashioned pasta?
