Our theme of this episode is warm noodles, full of the best of land and sea, to make cold winter days better. The port city of Nagasaki, on the island of Kyushu in southwestern Japan, remained open to foreign trade even when Japan closed itself off from the 1600s to the 1800s. As a result, Nagasaki developed its own unique food culture, and this week Rika will be making her own version of Nagasaki's famous noodle dish, champon.
