This recipe is designed specifically for frozen chicken cooked on the high pressure setting of an Instant Pot. The slow cooker setting will require thawed chicken and you will cook it for 4-6 hours on high or 6-8 hours on low. Also, with the Orange Marmalade, I prefer Smucker’s Natural Orange Marmalade Fruit Spread. Most often, I find it at Walmart, but you can get it on Amazon too.
