Host is the perfect word to describe Yayo and her sister, Hiroko, who demonstrated traditional Japanese cooking techniques handed down by their grandmother. I expected the cooking class to take place in a commercial-style kitchen like other cooking classes I had taken before. Instead, we were welcomed warmly into a well-appointed Japanese apartment. We left our shoes at the door, and were provided warm and fuzzy slippers. Yayo escorted us to a traditional tatami room, where Hiroko, all decked out in a classic Japanese kimono, prepared matcha (green tea) for us.
