Instant Pot Bone Broth

Optional Step to Enhance the Bone Broth: Heat up your pressure cooker over medium high heat (Instant Pot: press Sauté button and click the Adjust button to go to Sauté More function). Make sure your pot is as hot as it can be (Instant Pot: wait until the indicator says HOT).
Add 1 tablespoon (15ml) olive oil in the pot and brown the bones for 3.5 minutes per side. You may have to do it in two batches. Pour in ½ cup (125ml) cold water and completely deglaze the pot by scrubbing all flavorful brown bits with a wooden spoon.
Pressure Cook Bone Broth: Add 5 - 6 (212g) chicken feet (optional) and the rest of the ingredients in the pressure cooker. Close lid and pressure cook at High pressure for 2 hours + Full Natural Release (~45 mins). Open the lid carefully.
Strain Bone Broth: Strain bone broth through a colander or mesh strainer to discard the solids. Set aside the bone broth to cool.
Skim Fat: Use a fat separator to skim the fat. An alternative method is to place bone broth in the fridge until the fat rises to the top and form a layer of gel. Then, skim the layer of fat with a spoon. A gel-like texture after cooling is a good indicator of an excellent gelatinous bone broth.
Enjoy Bone Broth: Season with salt (if desired) and drink it directly. Or you can use the Bone Broth in place of stock.
Storage: Bone broth can be stored in the fridge for 3 - 5 days. If you are freezing the bone broth, use within a year for best quality.
