A Matter of Taste

Michael Mosley and James Wong explore the sensations, tastes and flavours we enjoy in our food. From luscious strawberries that deceive us into thinking they are sweeter than they actually are, to the tastiest French sea salt combined with caramel that delights the tongue. Together they unpack the wonderful evolutionary story of our food and our sense of taste and smell.

Michael heads to Spain to search for some of the most powerful tastes on the planet, whilst James travels high in the Peruvian Andes to discover how a bitter potato - a cousin of the humble spud - has been tamed to help the inhabitants survive the extreme altitude. Using the latest imaging techniques to take us inside our food, right down to the molecular level, Michael and James offer us a whole new way of thinking about taste: far more than being just delicious, it's actually a matter of survival.
