Heat up a wok on medium heat and once it’s hot, add in your cooking oil.
Once the oil is hot, add in the white parts of the green onions + the minced garlic and reduce the heat to medium-low heat.
Stir-fry this for about 20 seconds and then add in your corn kernels.
Stir-fry everything together on medium heat for about a minute.
Now add the sugar and water to the wok.
Stir-fry everything for another 30 seconds and then cover the wok with a lid.
Let it cook until the corn is almost done, roughly about 1 minute, and occasionally stir the corn to prevent it from sticking and burning at the bottom.
When the corn is almost done, remove the lid and add in your fish sauce. Stir-fry everything for another 10-15 seconds.
Now add in your margarine, stir-fry it for about 10 seconds, and then add in your dried shrimp, stir-fry it for about 30 seconds, and then cover the lid again for another 30 seconds.
Finally, remove the lid, stir-fry it for another 15 seconds, and then add in your green onions. Stir-fry everything for another 15 seconds before turning off your stove and transferring the dish to a bowl or plate and serving it.
