Set the Instant Pot on SAUTE function & set it on NORMAL heat setting.
Add oil & when the oil becomes moderately hot gently release the green curry paste and saute it for 30 seconds stirring frequently.
Now, pour the full fat coconut milk. Stir briskly to evenly incorporate the green curry paste into the coconut milk. Also add the fish sauce and check for seasoning, add salt accordingly.
De-glaze the pot with the help of a spatula scraping the sides and the bottom of the pot. This will help loosen any stuck food particles & hence, shall prevent the BURN error.
Bring the coconut milk to a gently simmer. Add the baby corns and the bamboo shoots. Give everything a quick stir. Add the de-shelled, de-veined shrimp/prawns.
CANCEL the SAUTE function. Close the lid of the Instant Pot and SEAL the valve. PRESSURE COOK on HIGH for just 0 minute.
Once the cooking cycle is over the Instant Pot will begin to beep. Immediately perform a quick pressure release (QPR) by manually moving the valve from the SEALING to the VENTING position. Once the metal pin drops open the lid of the Instant Pot.
Add the rest of the veggies. Give everything a good mix.
Turn off the Instant Pot and Cover and allow the veggies to rest for 5-10 mins. The residual heat will help cook the veggies slightly keeping them crisp tender.
Garnish with chopped Thai chilies and Serrano pepper (optional) and Thai basil which is also optional. Read NOTES below for more details. Enjoy!
