'Shiro-an'

Rinse Butter Beans and drain well. Place all Butter Beans into a food processor and make them into paste.

Add Sugar and pinch of Salt. Process until it gets smooth paste texture.

*Note: If you wish to cook Dry Butter Beans by yourself, I recommend to use Larger Butter Beans (Lima Beans). Soak the beans overnight. Next day, rinse and drain the beans, remove skins, then cook in water until absolutely tender.
