Press sauté on the instant pot and set the timer to 6 minutes.
Dry fry the coriander seeds, star anise, ginger, and licorice (if using), and stir for a minute so the spices release their aroma.
Add leek or onion, carrot, and celery. Cook for 3-5 minutes allowing them to brown and soften slightly.
Pour in 2 cups of water to stop the cooking process, followed by another 2 cups.
Add the remaining spices, and put the chicken on top, breast side up then sprinkle with the salt.
Toss in the spent corn cob, apple and the remaining 2-3 cups of water.
Add the coriander or parsley on top, close the lid and set to manual/pressure cook for 15 minutes.
Press cancel on the instant potand allow the pressure to release naturally for 15 minutes. If the silver float valve is still raised after this time, manually release the remaining pressure by pressing the pressure release button.
Carefully remove the chickenand shred the meat with two forks. Keep the frame to make a second batch of chicken stock. You can keep this in the fridge for a day or two or in the freezer for longer if you'll be making stock in future.
Strain the liquid (which is now your chicken stock) through a colander into a large bowl. You can also line it with cheesecloth or a nut milk bag if you want to ensure no debris comes through. If you're having the soup now, take some of the strained carrot and the shiitake to add to it then discard the rest of the veg and spices.
To assemble the soup add some of the shredded chicken, the reserved veg, and a big handful of baby spinach to a bowl. Pour over a couple of ladles of hot chicken broth, add a squeeze of lemon juice and follow with any seasonings and sauces you like. My go-to’s are a little soy, a dash of mirin, black pepper, a small squeeze of sriracha and a sprinkle of sesame seeds.

Notes
To make this a classic chicken noodle soup add some cooked rice noodles or egg noodles to your bowl then add the chicken, veg and ladles of hot soup on top.To make this on the stove top:
Heat a large pot with a lid over medium heat. You'll need at least a 5 - 6L (6 quart) capacity.
Dry fry the coriander seeds, star anise, ginger, and licorice (if using), and stir for a minute so the spices release their aroma.
Add leek or onion, carrot, and celery. Cook for 3-5 minutes allowing them to soften slightly.
Pour in 2 cups of water to stop the cooking process, followed by another 2 cups.
Add the remaining spices, and put the chicken on top, breast side up then sprinkle with the salt.
Toss in the spent corn cob, apple, coriander or parsley, and the remaining 2-3 cups of water.
Completely cover the chicken with water. Depending on the size of your pot, the 6-7 cups should be sufficient. If it's not - just top it up with a little more.
Place the lid on your pot and bring everything to a boil. Reduce heat to low, move the lid to the side a little so the pot is only partially covered, then simmer for 1 hour or until chicken is cooked through. You may want to skim the surface of the broth occasionally throughout the cooking process as scum can form there
Remove from heat once cooked then remove chicken and shred the meat with two forks. Keep the frame to make a second batch of chicken stock. You can keep this in the fridge for a day or two or in the freezer for longer if you'll be making stock in future.
Strain the liquid (which is now your chicken stock) through a colander into a large bowl. You can also line it with muslin or a nut milk bag if you want to ensure no debris comes through. I never bother with this. If you're having the soup now, take some of the strained carrot and the shiitake to add to it then discard the rest of the veg and spices.
