Gorgeous Fresh Water Chestnuts

This is fresh water chestnuts.  They look like a hard shelled flower tuber of some sort.  The first time I encountered it was back in South Viet-Nam.  The street Fruit vendor was selling an interesting strands of white round objects on a bamboo sticks.  Since I missed Japanese MITARASHI YAKI DANGO so much, I thought that was it!   Surprise! it was a crispy, sweet, fresh water chestnuts.  Yes, the good fresh water chestnuts, when peeled should be white, firm, and when bitten into, it is crispy and with some sandy texture like body.   Eat them fresh or chop them up and mix with ground pork to make sweet and sour meat balls or Lion Head meat balls, for example.  They will add a different dimension to the meat balls.  When you are peeling them with a pairing knife - in a round circular motion as though peeling apple, if there are any sign of 'yellow', cut that section off and discard.  After peeling them, chill them.  Eat them! 
So, Enjoy some chilled fresh water chestnuts during the summer.
