Sprinkle some salt on the bone-in chicken and gently scrub, then rinse the salt off with warm water and pat it dry using paper towels.
Place the bone-in chicken in the pressure cooker along with 4 cups of water, salt and pepper.
Cook the chicken according to the instructions provided in the manual. I cooked the chicken on hi for 30 minutes.
While the chicken is cooking, peel the turnip and cut it into large cubes and set it aside for later.
Cut the green onion to separate the green part from the white part of the onion. Then take the green part of the onion and cut it into small pieces and set aside for later use.
When the pressure cooker is finished, carefully open the lid and remove the cooked chicken, let it cool, shred it then set it aside.
After the chicken is removed, add the peeled ginger, ground cloves, cubed turnip, and spice pouch containing the cinnamon stick and star anise in the broth. The cinnamon stick and star anise are placed in a pouch to make it easier to remove them later.
Place the lid back on and pressure cook the turnip. Turnips are similar to potatoes as far as hardness goes, so follow the instructions in the manual for cooking russet potatoes for cooking the turnip. I cooked the turnip on hi for 2 minutes.
After 2 minutes, carefully open the lid, remove the spice pouch and add in the chicken broth, white part of the green onion and fish sauce to taste. Then turn the pot on low to simmer while preparing the noodles.
