I made them this past Saturday.
One of the reasons is it is more difficult, there aren't many books explaining that.... and then I guess the reason those books are not published is because it is not that popular nowadays. Two Japanese traditional wagashi ( sweets ) shops have torn down in the past 3 years..... so sad. I am calling myself " Anko Nanmin = Sweet Bean Jam Refugee, meaning looking for authentic wagashi and wandering around...."
I love Western sweets also, but green tea & wagashi combination is special.
Plus, wagashi ingredients are healthy, beans, mostly.
