Example Input: Adzuki ( or Azuki) beans are ment to be used in asian sweets. You can make sweet bean paste by boiling the beans for 30-40 min, (changing the water out at least twice) draining and mashing the beans with sugar.(strain the paste if you do not like the bean skins)  What you get is a paste that can be put on ice cream, fill pasteries or stuff into Mochi Cakes.
