Quick, easy homemade mixed berry jam made in the Instant Pot with just five ingredients and no pectin. Ready in about 15 minutes and perfect on toast, yogurt, or pancakes.
Ingredients
32ouncesmixed berries, frozen
1cupgranulated sugar
2tablespoonslemon juice
3tablespoonscornstarch
1 1/2tablespoonswater
Instructions
Add the frozen berries, sugar, and lemon juice to the Instant Pot. (It will look dry at first — the frozen berries release liquid as they heat.)
Lock on the lid and set the valve to the sealing position.
Cook on high pressure for 1 minute, then allow a natural pressure release.
Remove the lid and use an immersion blender to blend the jam until smooth.
In a small cup, mix the cornstarch and water into a smooth slurry, then stir it into the jam.
Press Sauté and let the jam heat and bubble until thickened, stirring as needed.
Cool, transfer to jars, refrigerate, and enjoy!
Equipment
Instant Pot or pressure cooker,
Immersion Blender
Mason jars or airtight container
Notes
No pectin needed — the cornstarch slurry thickens the jam.
Jam will continue to thicken as it cools.
Store in an airtight container in the refrigerator for 2–3 weeks.
Instant Pot canning is not recommended; refrigerate only.
