Place Instant Pot on high pressure (or manual) for 5 minutes then natural release until all pressure has released.
Mash strawberry applesauce with a potato masher or immersion blender until desired consistency.
Taste applesauce and add in desired amount of sugar.
Turn Instant Pot to Saute and cook for 5 minutes, stirring occassionally until sauce thickens slightly. This will look like a waterier consistency, but it will thicken a little more when cooled.
Enjoy immediately or refrigerate for up to 5 days.
Notes
*Use very ripe strawberries and gala apples to create a no-sugar added variety.
