If you don't have time to make broth (6-8 hrs) you can skip steps 1-5 and just use premade chicken broth, this isn't recommended though. If you arr making broth start by blanching the chicken scraps by dumping them in a pot full of water and bringing it to a boil.
You should get this mess at the top of your bowl. Scoop that stuff off, then drain the water and add enough fresh water to submerge ther chicken scraps.
Place over high heat. Add onions, chile peppers, mushrooms, ginger, green onion whites, miso paste and salt and bring to a boil. Then reduce to a slow simmer. Let that cook for 6-8 hours. Add water as the level drops at about the rate of two cups per hour. You should also use a ladle to skim the fat off the top of this broth, however don't overdo it. I only start to remove fat as the globules get bigger than a quarter. I think asian broths benefits from a fair amount of animal fat.
At the end of the simmer time,use a colander to remove the big stuff from the broth. Then to further clarify the broth, pour through a strainer lined with 2 layers of cheese cloth. You can see the kind of gunk you can pick up in the picture below.
Now you have your clarified broth. Thos should make about 10 cups. So if you have more liquid continue to boil until you've concentrated your broth down. At this point you can refrigwrate your broth for up to 5 days or freeze for up to a month.
When ready to eat some ramen season 1 pound chicken drumsticks and thighs with salt and garlic powder. Heat 1 tbsp sesame oil in a large sauce pan over medium-high heat.
Cook until golden brown on the outside and cooked all the way through (about 15 minutes). Set aside and shred half the chicken when they're cool enough.
While the chickens cooking prepare the fried shallots and ginger. Heat 1/2 tbsp sesame oil over medium heat in a heavy bottom pan until oil smokes. Add garlic and shallots and continuously move around until burnt bits begin to develops, about 2 minutes. Remove from heat and set aside.
Pour sake into the pan and scrape up any brown bits stuck on the bottom.
