Place the strawberries in the Instant Pot and add sugar. Let them steep for 20 minutes.
Add lemon juice, fruit pectin, and stir. Secure the lid and lock it into place.
Select the Pressure setting and cook on High pressure for one (1) minute. It will take some time for the Instant Pot to come to pressure.
Release the pressure when the cooking time has expired and allow the pressure to release naturally for about 10 minutes. Remove the lid and pulse the strawberries with a wand blender to break apart some of the berries.
Switch the Instant Pot to the "Sauté" mode and cook the jam for an additional 5-10 minutes, stirring frequently, until it thickens to your desired consistency.
Perform a gel test to ensure the jam has reached the desired thickness. Place a small amount of jam on a chilled plate and place it in the freezer for a minute. If the jam wrinkles when you push it with your finger, it has reached the desired consistency. If not, continue cooking for a few more minutes and test again.
Once the jam reaches the desired consistency, turn off the Instant Pot and let the jam cool for a few minutes.
Ladle the strawberry jam into the Ball Canning jars. Secure the lids. Cool the Strawberry Jam for two hours in the fridge.
