Wash the strawberry really well then pat it to dry using a kitchen towel. once it's dry remove the green leaf part and then chop them roughly.

After 30 mins open the instant pot. You will be some extra liquid. The sugar reacts with the strawberry and releases them. Add in the lemon juice and close the instant pot. Set 1 min in high pressure.

Let the pressure release naturally and then open the Instant Pot.

There will be more liquid in the jam now. Press the saute button and continue cooking the jam. Using the spatula mash the strawberry. Strawberries are really soft and they get mashed easily. You may also use an immersion blender and mash.

Keep stirring and continue cooking. The jam starts to thicken in some time and resembles a gel.

If you take the jam with a spatula it coats the spatula without falling apart this is the correct stage. You can switch off the Instant Pot. Let the jam cool completely. The jam thickens as it cools.

Once the jam cools completely transfer them to clean sterilized bottles for longer shelf life.
