Prepare the ingredients by thawing the rice cakes, chopping/dicing the scallions, onion, and zucchini, chopping the fishcakes to matchstick sizes, and mincing the pork.
In a pan, saute the garlic and scallions. Once fragrant, add the pork and saute well.
Add the onion and zucchini and mix well.
Make a well in the middle and add the black bean paste, fry for a bit then mix with the other ingredients.
Add cooking wine, soy sauce, oyster sauce, and black pepper. Mix in the seasonings thoroughly.
Add water, bring to a boil and taste.
Add the fish cake and rice cake and cook for 3 minutes until the rice cakes are soft and chewy.
Allow the water to reduce, meanwhile, make a slurry by combining potato starch and water.
Add the slurry slowly and mix right away to thicken the tteokbokki.
Once the sauce is nicely velvety, plate, serve hot, and enjoy!
