The briny fresh flavor of raw oysters on the half shell is enhanced by this simple Asian sauce. Serve wasabi (Japanese horseradish paste) on the side for those who want added heat.
When shopping for oysters, be sure the shells are closed and not broken. If they are open, tap them with your finger to see if they will close. Purchase and use only those that close. Use oysters soon after purchasing them; if you need to store them for a bit, put them on a tray and cover it with a damp towel. They can be refrigerated, if need be, up to three days.
