Add the beans back into the Instant Pot with 1 ½ cups of water.
In a separate bowl, add 1 cup of boiling water, salt, brown sugar, molasses, ketchup, pepper, dry mustard and stir. Add mixture to the Instant Pot. Rinse the salt pork well and add it in.
Set the manual/pressure cook button to 10 minutes. When time is up let the pressure release naturally for 10-20 minutes.
Stir the beans. Set Instant Pot to saute and let the sauce thicken and reduce down for about 10-15 minutes until thick, stirring occasionally.
Taste test and add more molasses or salt and pepper to taste.
