KUALA LUMPUR: Once a teacher, always a teacher!. When former private tutor Kelsey Lee learned the art of making the traditional Japanese dessert called wagashi, she wanted to teach others how to craft it.. Walking into Yu Wagashi is an experience in itself. There is a sense of serenity in the air of this teaching centre and the neatly arranged rattan chairs, Japanese-inspired paintings on the wall and colourful kimonos everywhere mimic a typical Japanese setting.. Greeting you at the door is Lee herself, clad in a kimono. She is the owner of Yu Wagashi and started teaching wagashi courses
