*This recipe was created using the 6-quart instant pot. If you are using a different size pot or a different pressure cooker brand entirely, cooking times may be off by a couple of minutes.
**Live at High Altitude - Because water boils at a lower temperature at high altitudes, and pressure cooking requires water to boil in order to work, some foods may need a little more cooking time. When pressure cooking at high altitudes you want to make sure to add 5 percent to your cook time for every 1,000 feet above 2,000 feet elevation. For example, when we lived at 4,000+ feet I would add 10 percent to my cook time. For a recipe that called for 20-minutes of cooking time, I would then cook for 22 minutes. When pressure cooking, 1-2 minutes can make all the difference in a recipe, unlike when cooking by traditional methods.
