Process materials
When you buy oysters, put them in a bowl of water and use a brush to rub the outer shell to remove all the dirt on the shell and then wash it again with clean water.
Next, you use scissors to cut the thin shell around the oyster and then use the tip of the scissors to separate 2 pieces of oyster shell. Only keep the shell that has oysters on it, and discard the shell that doesn’t have any meat on it.
Onions you peel, cut into small pieces. Onions, you remove the roots, wash and cut into small pieces. The quail eggs you break, put in the bowl first.
