Heat a large frying pan (it will need to fit the soup later) on medium low and add ½ tbsp sesame oil. Once hot, add 30 g Japanese leeks (naganegi), 1 red chili pepper(s), 1 tbsp ginger root and 1 clove garlic and fry until fragrant.
Once fragrant, turn up the heat to medium and add 50 g ground pork. Fry until browned.
Next, add 1 tbsp chili bean sauce, 1 tbsp yellow miso paste (awase miso), 1 pinch ground black pepper and 1 tbsp ground sesame seeds. Mix well and stir fry for 1 minute.
Add 300 ml water and 1 tsp Chinese-style chicken bouillon powder, then bring it to a boil.
Once the liquid is boiling, turn down heat to simmer and add 1 tsp soy sauce and 1 tsp sugar.
In a small separate bowl, mix the potato starch and cold water to make a slurry (1 tbsp water and 1 tsp potato starch). Add the slurry to the soup and cook until slightly thickened, stirring continuously.
Once thickened, remove from the heat and place a lid on top of the pan to keep it hot until serving.
Cook 2 portions ramen noodles according to the instructions on the packaging. Once the noodles are cooked, pour them into a colander to drain the water and rinse with warm running water to remove excess starch.
Transfer the noodles to mixing bowl and drizzle with 1 tsp sesame oil. Mix until evenly coated and then divide onto serving plates. Top each portion with 1 tbsp green onion, 2 tbsp shredded sushi nori seaweed "kizami nori" and your choice of toppings.Pour the soup into individual dipping bowls and top with 30 g garlic chive(s), 1 red chili pepper(s), 1 tsp sesame seeds to garnish and 1 dash chili oil. Enjoy!
