Specifically, depending on the size of the oyster, the baking time is slightly different, according to the actual situation and their own requirements to control the time. Although oysters are most flavorful when eaten raw, in reality, it is a bit risky to eat them raw, so it is recommended to make sure they are cooked before eating them.
Generally roasted until you hear the squeak, then turn the oysters over and add the sauce, and grill them a little. Oysters are usually grilled over charcoal at upwards of 100 degrees Celsius, which mostly kills the bacteria.
