Begin by trimming the fat from the joint, and slice the beef into 1/2" thin strips
Mix salt, ground ginger into a bowl, then use to season meat
Switch Pressure Cooker to Browning Mode and add the Oil from the choice of oils above.
Once the oil is heated and shimmery but not smoking, add the beef in batches and brown all sides. Take care not to crowd the beef, so that all sides get browned.
Return the browned beef strips and any plate juices to the Instant Pot / Pressure Cooker.
Quickly coat the Brisket Strips in the Sauce
Secure the lid and set to High Pressure Setting for 35 Minutes.
Use default Meat/Stew setting on the Instant Pot.
Once complete allow the Instant Pot to self release steam
I did not complete this step but if you would like to thicken the sauce, use 4 tbsp of tapioca starch or arrowroot with 4 tbsp of water, mix until smooth, then add it to the pressure cooker, and stir well. Then switch to saute cooking cooking uncovered for about 5 minutes.
