Have you heard Azuki bean ? http://en.wikipedia.org/wiki/Azuki_bean
Eastern Asian knows it but Japanese Azuki bean recipe is interesting.
I boil them for long time until bean skin become soft.
After that,I add sugar and a little salt.
I will get Azuki bean paste at last.
I believe Azuki bean paste is better than Chocolate,which is low fat.
I love "Taiyaki" very much !
