I love this dessert of shaved ice with red beans or other combinations of sweet beans or fruit. The only place I've come across it in SF is at the Double Rainbow at 23rd and Irving. Does anyone have any other leads?
To shave the asparagus, hold the tough stem in your fingers and start at the green tender part. Peel toward the head with a sharp peeler to make thin ribbons. Medium or thick asparagus works best for shaving.
