Step 1

In a medium saucepan, combine cranberries, water, sugar, orange zest, cinnamon stick and salt.

Step 2

Simmer the mixture over medium heat, stirring occasionally, for about 10 minutes. The sauce should be slightly thickened, but still runny. It’ll thicken more as it cools.

Step 3

Remove from heat and discard cinnamon stick.

Step 4

Stir in orange liqueur.

Step 5

Cool completely and serve.

Step 6

To make it in Instant Pot: Put all the ingredients, except for orange liquor, in inner pot of Instant Pot. (Note: only add ½ cup of water.)

Step 7

Set the Instant Pot to Manual/Pressure Cook for 1 minute on High. (It took about 8 minutes for my IP to come to pressure.)

Step 8

Once the time is up, allow the pressure to release naturally for 10 minutes, which means you don't need to do anything. Then carefully turn the valve to venting. Once the pin drops, carefully open the lid.

Step 9

Hit "cancel" button, and then select "sauté" function. Stir in orange liqueur and cook the sauce for about 5 minutes, stirring frequently, until thickened. Transfer into a jar and cool completely.
