Remove the skin on the chicken, use a kitchen meat pounder to smash the chicken and to break the bone. Use a sharp knife to make several deep cuts to the meat throughout the piece.
Add the chicken and the other ingredients to a bowl or a zip top bag and stir or massage the ingredients into the chicken. Place into the fridge for up to 24 hours. Allow to marinate for a minimum of 2 hours.
Use a metal or glass bowl that fits into your pressure cooker turned right side up, be sure to leave enough of a gap between the larger bowl and the pressure cooker so that you can add water to the cooker. Invert a smaller bowl into the larger bowl. Place the chicken onto the smaller bowl. Avoid putting the herbs into the pressure cooker if possible.
Carefully, so as not to splash water into the inside bowl, add water outside the large bowl into the pressure cooker pot. Fill to ½ way up the side of the larger bottom bowl.
Apply the lid and pressure cook for 59 minutes. Allow a natural release. (if using instant pot, click the manual button and then set the time for 59 minutes. Do not release the pressure yourself, let the pressure come back to room pressure on it's own).
When you remove the pressure cooker lid, you will find that most of the liquid is trapped in the inverted bowl. Be careful as the pans are likely still very hot. Use tongs to remove the chicken pieces, allow everything to cool or use hot pads to remove the bowls. If you note that there are chicken pieces in the essence, pour through a strainer to remove. Pour the essence into a lidded container to refrigerate.
