Instant Pot: Add the bones, onion, ginger, spices, water, fish sauce, sugar and salt to the Instant Pot. Cook on high pressure for two hours or use the Broth function.
Let the Instant Pot natural release fully or natural release 30 minutes then turn to vent. Be careful as a lot of steam will be released.
Remove the beef bones, ginger and onion and strain the broth into a large pitcher or bowl. Let the broth settle for 15 minutes then skim off the fat. Or let the broth completely cool, refrigerate and remove the solidified fat layer.
