Place all the ingredients for the chicken marinade in a bowl. Mix well to coat the chicken. If time permits, allow the chicken to marinate for at least 1 hour.
Preheat the oven to 425°F / 218°C, and place an oven rack in the top third of your oven. Line a baking sheet with parchment paper.
Place the chicken pieces on the baking sheet, skin side down (or smooth side down), evenly spaced apart. Then place the baking sheet in the preheated oven (upper third).
Let the chicken roast for 15 minutes. While the chicken is cooking, mix the brown sugar and dark soy sauce for the glaze, and start making the ramen.
After 15 minutes, flip the chicken pieces over and spoon the glaze over them. Let the chicken cook for a further 10 - 15 minutes. Then remove from the oven and let them cool down.
Slice the chicken and set aside.
While the caramelized soy chicken is cooking in the oven, make the ramen base.
Place two saucepans on the stove.
In one saucepan (Pot 1), place the stock, ginger, garlic, spring onions, chili (if using), soy sauce, and mirin. Stir and cover the pot. Let it come to a boil at medium high - high heat. Then lower the heat to medium and let it simmer for 20 - 25 minutes. Taste the base and add more salt if needed.
While Pot 1 is simmering, add water to the second pot (Pot 2), and bring it to a boil. Add the dried noodles to the boiling water and cook according to package directions. Drain the noodles and divide into 4 bowls and set aside.
When the ramen base in Pot 1 has cooked for about 20 - 25 minutes, strain to remove the garlic, ginger, chili, and spring onions. Add the strained stock back into the pot and add the mushrooms (fresh and reconstituted dried mushrooms), and let it cook for a further 5 minutes until the fresh mushrooms have softened.
Make ramen eggs the day before, according to this recipe. OR make regular soft boiled eggs to top your ramen bowl.
To make regular soft boiled eggs - bring a pot of water to a boil. Lower 4 large eggs carefully into the water and cook the eggs for 6 - 6 ½ minutes. Immediately place the eggs in cool running water or an ice bath for a few minutes. Peel and set aside until ready to serve.
Wash the greens and cut them in half, or into sections if necessary, to separate thick stems from the leaves. Place the greens in a bowl and drizzle a little soy sauce and sesame oil (and garlic) on top. Toss to combine.
Cover and microwave in 1 minute increments until the greens have softened, but not too wilted.
Evenly divide the hot stock between the four bowls with ramen noodles. Top with the steamed greens, sliced soy chicken, ramen eggs, spring onions, radishes, and other toppings you like.
