Wash and drain the mumallaengi in cold water a couple of times. Soak it in cold water for 7-8 minutes.
Strain and squeeze out excess water.
Heat up a pan over medium high heat and sauté the mumalaengi with 1 teaspoon vegetable oil for 1 minute. Remove from the heat. Set aside.
Combine garlic, green onion, fish sauce, hot pepper flakes, rice syrup in a mixing bowl and mix it well with a spoon.
Add the mumalaengi and mix it well by hand. You can wear a disposable cooking glove to prevent your hand from sore.
Sprinkle with sesame seeds. Transfer some to a serving plate and serve as a side dish with rice. The leftovers can be stored in the fridge up to 1 month.
