Food Unwrapped - Season 9 Episode 8

Jimmy's off to Israel on the trail of an elusive fruit - the fresh date. If raisins are dried grapes and prunes are dried plums, then what exactly are dates? Jimmy's search for the answer takes him to a vast water purification plant, where they harness the raw sewage of Tel Aviv to turn barren desert into fertile farmland. Kate flies to California to investigate why almond butter is more expensive than other nutty spreads, and discovers a combination of extreme weather and global economics have made the price of almonds go completely nuts. And Matt's in Scotland, investigating haggis. He makes a surprising discovery about the dish's true origins - and then faces the nerve-shredding ordeal of delivering some highly unwelcome news to an unsuspecting audience.
