About this episode
Simon Jack brings you tales of making more from what we have already got - be that using plant protein to make eggless mayonnaise or harvesting energy from crop by-product like straw. In Lesotho they are using their abundance of freshwater to farm trout for Japanese sushi. But there is a spot of indulgence on the programme too. Simon speaks to Dunkin’ Donuts CEO Nigel Travis, who says they offer healthy options, and we hear about the growing appetite for craft beer in South Korea.
