Wash rice. Add the rice to a bowl, and add enough water to cover the rice. Swirl the rice around. Drain and repeat a few times until the water is clear. Let drain and dry.
Turn on Instant Pot with Saute function. When hot, add 1 -1/2 teaspoon vegetable oil and ginger. Saute for 30 seconds, add rice and 1 teaspoon salt. Stir to coat rice with oil approximately 1 minute.
Add chicken pieces, bouillon, and rice wine to the pot . **If you are in a rush or feeling lazy, skip sauteing the rice and ginger. Just throw them into the pot, fill with enough water until it reaches the 10 cup mark in the Instant Pot.
Turn off saute, close the lid and make sure the knob is on "Sealing". Choose the "Porridge" button and set the time to 20 minutes.
While congee is cooking, shred ginger and slice scallions and place in small bowls for serving.
When the time is up on the timer, turn the Instant Pot off. Wait 15 minutes natural release before turning the knob from 'Sealing' to 'Venting'. Rice soup tends to splatter a lot, do not do a quick release.
Remove the chicken from the pot, when it is cool enough to handle, shred the meat and discard the bones. If the jook seems thin, turn saute' function on (without the lid on) and cook until desired consistency. If it is too thick, add water or broth.
Add the chicken back into the congee or put it in a bowl and let folks add at the table. Taste, add salt if necessary.
Ladle into bowls and top with desired amount of ginger, white pepper, sesame oil and scallions. Let folks add their own.
