After the ribs fly into the water, rinse it, put it into the pressure cooker, add enough water, put in the corn, scallions and flat ginger, cover it, simmer it in the pressure cooker, then turn to medium heat and cook for 20 to 25 minutes. It takes a little longer to burn the ribs.
Turn off the fire, wait for the pressure cooker to naturally trip, open it, remove the scallion and throw it away, then add the longan, radish, scallions and the right amount of salt. After the fire is boiled, turn it into medium and small fire for 15 minutes (without high pressure function). Just sprinkle with chopped green onion before the pot.
