Trim the spinach roots (if any) and wash the spinach in cold water thoroughly.
Boil water in a pot or saucepan for 5 to 7 minutes. Add 1 teaspoon of salt. Once the water starts boiling, plunge the spinach into the pot and let it cook for 30 seconds.
Drain the water and rinse the spinach under cold water for 1-2 minutes. Gently squeeze the spinach to remove excess water.
Divide the spinach into 2-3 pieces using a knife. (If using baby spinach, you can skip this step.)
Add the seasoning sauce and mix well with your hands.
Serve with a bowl of rice and an assortment of Korean side dishes for a complete meal.
