• Place all of the ingredients in the Instant Pot and pour in enough waters so that they are not quite covered. Make sure not to use too much water otherwise your broth will too diluted, will lack taste and will have fewer health benefits. The amount of water will obviously vary depending on how many bones you have, so I can’t give you an exact measurement.
• Turn your Instant Pot onto the Soup/Broth setting and set the time for 4 hours. Make sure the Keep Warm function is on. I usually set my Instant Pot to cook the bone broth overnight, so it will cook for 4 hours and then be kept warm until I am ready to strain it. This lets the broth continue cooking very gently which again helps with the flavour. Sometimes, if I have done my broth earlier in the day, I will set it to cook for another 4 hours, especially if there is a large amount in there. With bone broth, the longer you cook it, the better it is!
• When your broth has finished cooking, put a colander over a large saucepan and pour the contents of the Instant Pot into the colander to strain the broth. Make sure that your saucepan is large enough to hold all of the liquid. If it is not, do this step in two gos.
• There may still be some bits in the broth, this doesn’t bother me but, if you prefer it to be completely strained, you will need to strain it again through a fine sieve.
• Pour your strained bone broth into containers and leave to cool.
• Once your bone broth is completely cooled in its containers, you can keep them in the fridge for up to 5 days or in the freezer for up to 6 months. 

Other cooking options

• Dutch oven or large saucepan – cook on the stove for anywhere between 4 and 12 hours. Some people leave their broth cooking for 24 hours but I would prefer not to have anything cooking on my gas stove over night.
• Pressure cooker – I would suggest cooking for 4-6 hours once it has come up to pressure. Make sure you turn the stove right down to low once it is at pressure.
• Slow cooker – when I make bone broth in the slow cooker, I will let it cook for at least 8 hours. If you can leave it cooking for 24 hours, that would be even better.
