By using the appliances, we essentially exploit the high-pressure environment inside the cookers to enhance the temperature and make the foods getting cooked faster. However, when you get to a higher altitude, the pressure level will drop down, making the normal calculations for your instant pot recipes no longer accurate. So, you’ll need to adjust the cooking timer on your pressure cooker to make sure that your dishes can come out fine. A general rule of thumb is that you should increase your cooking timer to 5% when reaching the 3000-ft mark. And after that, just add 5% more to your multiplication after reaching 1000ft higher. For cooking at 2000-ft altitude and below, you can forget about the rule or give your pressure cooker just a little more cooking time, since it won’t have too many effects on the final dishes.
