Mizuyokan in bamboo

Today in my Ladies class (housewives who have traveled lots and have time on their hands for interesting hobbies and learning English), we were talking about summer recipes. One student brought in a special jelly (called mizuyokan) that she had made at home. Here's how it looked at first (jelly inside):
And then this is the jelly that was inside the bamboo:

The jelly is made from Japanese gelatin (from seaweed) and red bean paste with a little sugar and salt added. The mixture was then put in pieces of bamboo (that the woman has growing in her backyard). It's chilled and nicely wrapped in a leaf.

To get the jelly out after, we just punched a hole in the bottom of the bamboo with a sharp metal pick and the blew and the jelly came out. It was a fun and delicious snack.
