Select PRESSURE COOK mode on instant pot and adjust timer to 25 minutes. VERY IMPORTANT NOTE – I have used "freshly pulled" raw unsalted green peanuts. The variety of peanuts we get in India cooks fast comparatively. Cooking time for peanuts vary widely on the maturity of the peanut an it's variety. Freshly pulled peanuts cooks faster. I have tested over years and noticed it always cooks in 20-25 minutes. I know some will be surprised to hear I can cook peanuts in 25 minutes, but I believe the variety of peanuts vary from country to country. Green peanuts is the US and other countries usually needs more time to cook. If you are in The US, Canada or other countries, Please adjust your cooking time to 75 minutes and do quick pressure release.
Once cooking time is done, allow it for 5 minutes NATURAL PRESSURE RELEASE.
Carefully turn pressure valve to VENTING positing for manual release of pressure.
Do taste test to check for salt and seasoning, adjust to suit your taste buds.

To eat peanuts – Pick a peanut and gently squeeze the shell until it pops open. Let the juices run down – beware of messy, dripping fingers and elbows. Pull apart the shell into two, pick the legume and eat it, discard shell.
Serve immediately, while still warm, the BEST WAY TO SERVE.
