Recipe Notes
Note: In a non-pressure cooker I've always cooked my chicken adobo equal parts soy sauce, water, and vinegar but it is a little tricky in the pressure cooker. The dish might need a lot more salt afterwards.
Tip: You can throw in frozen chicken! Do not change the cooking times as it will just take longer to come to pressure. You may have a hard time browning the chicken in the beginning so if this is the case, skip this step. Just throw in your frozen chicken and other ingredients. I like to brown my meats to "seal" them but this is optional and not a necessity.
P.S. You can make this with pork spare ribs too! Personally, pork adobo is my favorite adobo.
