Wash the chicken well and exfoliate with salt both inside and out. Pick out the feather bits, trimming away the fats by the opening (keep aside), trim the neck fats (keep aside)
Trim the bits on the parson's nose (look at pic) don't eat that!
Remove the skin from the feet area. Do not cook that! Save the feet bones to season your broth.
When cleaned, massage first the rice wine into the insides of the chicken then rub all over with sesame oil. Insert in the cavity the spring onions and ginger. Your chicken is now ready for the pot.
Bring a pot of water to the boil. Place your chicken breast side down and bring your water back to boil and let it boil for 10 minutes then turn heat off. leave the chicken to poach for 30 minutes. Then remove the chicken and dunk into icy cold water immediately. This is to tightens the pores on the skin, to stop the cooking process and in doing so your chicken skin will be having that special 'jelly crunch' texture.
Drain your chicken after about 10 minutes and rub all over with sesame oil. Set chicken aside ready for chopping later.
