When the oil is hot, add minced ginger and garlic. Saute until aromatic, for about 30 seconds.
Add sliced mushroom to the pan and cook it until it has softened.
Add stock and water to the pan.
Add soy sauce, fish sauce, miso. Mix well. Check the seasoning and add salt if required.
Simmer the broth and let it simmer for 5 minutes.
While the broth is simmering, start making spicy pork.
In a small bowl mix all the ingredients for Spicy pork, except pork.
Heat 2 teaspoons of oil in a pan. once hot add minced pork. Cook for 2 minutes.
Stir in the sauce to the pork. Cook for another 4-5 minutes until the sauce has reduced and the pork is cooked through.
Now switch to the soup broth. When it comes to a slow rolling boil add ramen noodles blocks and sliced bok choy.
Cook the ramen for 3 minutes. It is ok if the ramen is not cooked fully. The ramen will continue to cook even after the flame is off and will be fully cooked while serving.
