The Mid-Autumn Festival, Moon cake or Lantern festival is celebrated on the 15th day of the 8th Lunar calendar i.e.: 3/10/2009.
The offerings for the Moon Goddess are Moon cake, Taro, Lengkok, Chestnut, Pomelo, Peanuts, Chinese tea......etc.Of all the offerings, I am fascinated with the Lengkok (water caltrop-trapa natans) which can be eaten and can be make into a spinning top (video).
To savor it's nutty flesh-crack it up with a hammer.
