Rinse the soybean sprouts 2–3 times under running water.

Finely chop the green onion.

Boil 5 cups of water in a pot and add 0.5 tbsp of coarse salt.

Once the water is boiling, add the rinsed soybean sprouts and cook for 4–5 minutes.

Remove the cooked sprouts with chopsticks and let them cool naturally in a colander.

Place the warm sprouts in a large bowl and add minced garlic, green onion, red pepper flakes, salt, sugar, sesame seeds, and sesame oil.

Wear sanitary gloves and gently mix the sprouts with the seasoning.
