Torkjell Berulfsen travels around the world for the following foods: Salt, sugar, coffee, tea, chocolate and spices. Each of the food has amazing stories of war and love, emergence of nations, the empire's fall, and most things that make life meaningful. Also, we can track some city states, a superpower, big companies, insane money sums, senseless laws and orders, an inexhaustible source of anecdotes and puzzles for the fight foe those commodities.—chribren
