North Korea is obsessed with Choco Pies from South Korea. There’s a black market for them, and factories once used them to pay worker bonuses. In 2010, The Chosun Ilbo reported that choco pies could fetch as much as US$9.50 on the North Korean black market. In 2014, S Korean activists sent 10K pies to NK with helium balloons. After an injured NK defector crossed the DMZ in 2017, he was given a lifetime supply.
