Coriander Seed (芫荽籽) Ketumbar in Malay

In my recipe for Nonya Dumpling (http://werynice.com/home/?p=369), a key ingredient is coriander seed grounded into powder.  Here is picture of how the seed looks like, and it is rather inexpensive.  I got a bag of 500g at S$2.50 from Waterloo Street Market.

You can just grind them raw.  I prefer to rinse them in water and scope up those that float (anything sink is either sand or dirt), and discard any twigs.  Then sun dry them under hot sun, followed by toasting them on a hot frying pan till you can smell the fragrant of the spice.  Then grind them into powder and keep in air tight container. This is also a key ingredient to seasoning Satay meat.
