Meet Hana Etsuko Dethlefsen. She's been making Japanese food her whole life, and showcases the cuisine beautifully in her first episode of One World Kitchen. She introduces us to Japan's most important culinary philosophy: Respect the ingredient. That is, use quality ingredients and do as little as possible to them to let them shine. Hana also shows us how to make two of the most popular Japanese foods at home: sushi and tempura. The tempura is light and airy; and hand rolled sushi is surprisingly easy to make.
