Method
In a pot, bring 500ml of water and 1 tsp of salt to a boil.
Add the spinach and blanch for exactly 20 seconds.
Rinse the blanched spinach quickly under cold water, then squeeze out excess water.
Place the spinach in a mixing bowl and add minced garlic, tuna extract(or Korean fish sauce or soup soy sauce) and sesame oil. Gently mix by hand.
Sprinkle with toasted sesame seeds to finish.
