Back to the broth. After 10 minutes of gently simmering, discard the anchovy-kelp broth packets. Now raise the heat to a MEDIUM-HIGH.
Place-in all of the mushrooms.
Then drain the soaking Tteok (rice cakes) - and place them into the soup as well.
Wait for the pot to come to boil. Once it does, let it boil away for 2-3 minutes. (Give it an occasional stir so the rice cakes don't stick to the bottom of the pot.)
After 2-3 minutes, let's season the soup. Add in Soup Soy Sauce (1 Tablespoon)
Then the Perilla Powder (8 Tablespoons). Give it all a good mix.
Now, add-in the diced spring onions and diced chili slices.
Give the broth a taste and season to taste. (We added 2-3 pinches of kosher salt!)
Finally, give the starch water another good mix with your spoon. Then pour it in - around the pot - in a circular motion.
Let the soup cook for a final minute - so it can slightly thicken.
Turn off the heat.
Scoop into a bowl and enjoy - Bon Appetit!
