To be honest, you can use any type of oysters you want.
They all work the same and will taste equally as delicious.

How To Make Taiwanese Oyster Omelet
Making the Taiwanese Oyster Omelet / O Ah Jian / 蚵仔煎 is a relatively simple thing to do.
The process to make this dish is as followed:
First, you need to prep your oysters.
If they are already pre-shucked then you can simply set it aside for now. If they are not shucked however, you will have to shuck them yourself.
Shucking an oyster is a pretty simple thing to do. Here is a quick guide on how to shuck an oyster.

Now that you have your oysters all ready, its time to prep the eggs.
Grab a small bowl and crack 4 large eggs into it. Add some salt and white pepper into the egg mixture and stir things around. Then set it aside.

Now grab your baby bok choy or any other mild-tasting leafy greens and chop them into thin slices. Then set it aside.
Grab your scallion/green onion and chop it into tiny pieces, then set it aside.
Now it’s time to make the omelet.
Pour 1 tablespoon of oil into a skillet over high heat.

Once the oil is hot enough, you’ll want to add in half of the oysters into the pan. That should be 4 oysters if you are using 8 total.
(I cut my oysters up, but that is totally optional)

Let the oysters cook until they appear slightly firm. This should take about 1 minute.
While your oysters are cooking, you’ll want to grab another small bowl and fill it with the cold water and sweet potato starch. Make sure to stir things around.

Then pour half of the potato starch mixture into the skillet with the oysters. Let the mixture bubble around for a few seconds.

After the mixture starts bubbling, you’ll want to take your egg mixture and pour in half of the mixture into the skillet.

Let the egg mixture bubble for a few seconds while making sure to scrape the running edges towards the center to for a rounder, neater shape that is about 5 to 6 inches in diameter.

Place your chopped baby bok choy and scallions on top of the omelet.

Take a peek at the underside of the omelet by lifting it up a little with a spatula. While you are doing that, make sure to loosen the edges all around. Once the underside is lightly browned and the edges are loose, carefully flip the entire omelet over.
After you had flipped it over, you’ll want to cook on the opposite side of the omelet until the bottom is lightly browned. This should take about a minute or so.
Flip the omelet over again when it is done cooking and serve it on a plate.

Drizzle the top of the omelet with some Hai Shan Sauce and serve immediately.
Repeat the process with the other half of the ingredients until you have made both omelets.

How To Keep/Store It For Later
Storing this Taiwanese Oyster Omelet / O Ah Jian / 蚵仔煎 is a relatively simple thing to do.
However there is something you should know beforehand.
For instance, once cooked, this oyster omelet should not sit out in room temperature for more than 2 to 3 hours. I would suggest if you are not going to finish it, to immediately put it in an air-tight container or wrap it with plastic wrap and store it into the fridge.
This oyster omelet should keep well in the fridge for up to 3 days.
As for freezing, I would not suggest you to freeze this omelet. Mainly because once frozen, the oysters will turn rock hard. And when thawed, the oysters will become insanely hard and rubbery.
So do not freeze this dish if possible.
