Vietnamese Scallion Oil (Mỡ Hành)

On stovetop:

1. In a heatproof bowl, combine the chopped scallions, salt, and sugar.
2. Warm up neutral oil in a small saucepan over medium heat.
3. To check if the oil is hot enough, dip the pointed end of a wooden or bamboo chopstick into the oil - if it sizzles, the oil is ready.
4. Pour the hot oil over the scallion mixture and stir thoroughly for about 30 seconds, ensuring the scallions are well-coated with the hot oil.
5. Allow the scallion oil to cool to room temperature, then transfer it to a jar or another container.

With microwave:

1. In a microwave-safe bowl, combine the chopped scallions, salt, and sugar.
2. Pour the neutral oil over the mixture and give it a mix.
3. Cook the mixture in the microwave on high for 30 seconds.
4. Then, stir well and microwave the mixture for an additional 30 seconds. Your Mỡ Hành is ready to go.
