Heat up the barbecue until it is very hot then place the unopened fresh oysters on to the lightly oiled grill and close the lid.
After about 3 minutes check to see if the oysters are open.
If the oysters are open then detach the oysters from the top shell using an oyster knife.
Then loosen the top shells and discard these.
Then you simply need to place a spoonful of the Hogwash sauce you have made over each one before serving them.
In order to make the Hogwash place the seasoned and natural rice vinegar into a bowl with the shallots, lime juice, jalapeno chili and cilantro and mix well together.
You should make this before you actually begin cooking the oysters, as it needs to go into the refrigerator for at least an hour.
