In the Instant Pot insert, whisk together the cup of mango juice with the ginger, garlic, miso and sugar. This heavenly mixture will bring out the best of the mango flavours.
Add in the chicken, peppers and baby corn and give it a good stir to coat it in all those delicious flavours.
Seal the Instant Pot lid, making sure the valve is closed and select Manual High Pressure for 4 minutes.
While the chicken is cooking its way to perfection, let's prepare the sauce. In a separate bowl, combine the remaining mango juice, lime juice, and cornstarch, giving it a good whisk until the cornstarch is dissolved.
Once the cooking time is up, manually release the pressure valve and carefully remove the lid. Select the Sauté function and add the cornstarch mixture into the pot. Stir for about 3-5 minutes until the sauce starts to thicken. Remember, the sauce will continue to thicken as it cools. (Note: before you add the cornstarch mixture the liquid in the pot may look clear like water...dont worry! lol)
Stir in the mango chunks and let them warm up briefly in the sauce.
Your dish is ready to serve!
Enjoy
