While the pot is heating, slice the meat into 1/4 inch thick slices and place into a bowl.
Sprinkle potato starch over meat and thoroughly massage into meat.
Add oil to hot pressure cooker.
Place meat into pressure cooker and don't touch for 10 seconds.
Flip over or stir meat and sear the other side. The meat should easily release from the bottom.
Add Shaoxing Wine and deglaze the bottom of the cooking pot. This means to use a high heat resistant spatula and scrape up anything that might have been stuck on the bottom of the pot.
Pour two cups of fresh water in with the rice and cover (if you have the lid with the steam holes, otherwise, don't worry about covering).
Lock on lid and close pressure valve. Cook at high pressure (most machines default to high pressure) for 3 minutes.
When Beep is heard, wait 10 minutes and then release the rest of the pressure.
Remove lid and remove bowl of rice and trivet. Set rice aside to finish steaming.
Turn off heat and drizzle sesame oil in pot, stir. There should be almost no liquid, as the sauce should cling to the meat.
Serve over rice and garnish with chopped scallions.
Notes
Type of Beef and Slicing the Beef
If using chuck roast, slice meat into very thin strips, about 1/8 of an inch.
If using sirloin, flap meat, flank steak or skirt steak, slice meat into 1/4 inch strips.
For a less spicy version, add the red peppers when you add the broccoli. Red peppers are very hot and just for flavoring. Most people push them aside.
Sesame Oil
Sesame oil is not a high index oil. It can taste spoiled, rancid and odd after cooking.
Therefore, even with a short cook time, make sure to add it to the dish after pressure cooking and then mix through. This way, the flavor of sesame will be present.
Another nice condiment for the Mongolian beef is to have a bottle of Toasted Sesame Oil on the table for individual persons to use.
Add in Suggestions
Thinly sliced carrots
Mushrooms
Water Chestnuts
Broccoli - if adding in broccoli, add it in after pressure release and at the before adding the oil. The residual heat will cook the broccoli, so stir it in until desired tenderness is achieved. Then stir in the sesame oil.
