Ingredients You’ll Need

Here’s the full list of ingredients to make your own Instant Pot Mixed Berry Jam:

• 32 oz frozen mixed berries (or 2 lbs fresh berries)

• 1 cup sugar

• 2 tablespoons lemon juice

• 3 tablespoons cornstarch

• 1½ tablespoons water

Ingredient Notes:

• Mixed Berries: A combination of strawberries, blueberries, blackberries, and raspberries adds complexity and balance. You can use pre-mixed frozen berries or create your own blend.

• Sugar: Adjust to taste depending on the sweetness of your berries.

• Lemon Juice: Enhances flavor and helps the jam set.

• Cornstarch + Water: This simple slurry thickens the jam without the need for added pectin.

Kitchen Equipment Needed

You won’t need any fancy equipment to make this jam. Just the basics:

• Instant Pot (any model with “Manual” and “Saute” functions)

• Potato masher or immersion blender

• Small mixing bowl

• Measuring cups and spoons

• Spatula or wooden spoon

• Airtight glass jars or containers for storage

Step-by-Step Instructions

1. Add Ingredients to Instant Pot

Pour the frozen mixed berries, sugar, and lemon juice directly into the Instant Pot. Let the mixture sit for 10 minutes. This allows the sugar to draw out the juices from the fruit.

2. Pressure Cook

Secure the lid and ensure the valve is in the sealing position. Set the Instant Pot to Manual/High Pressure for 1 minute.
After the cooking time ends, allow natural pressure release for 15 minutes, then do a quick release to release any remaining pressure.

3. Mash or Blend

Open the lid and use a potato masher or immersion blender to break down the fruit to your desired texture. Chunky or smooth—it’s your call!

4. Thicken the Jam

In a separate bowl, combine the cornstarch and water to create a slurry. Stir this mixture into the fruit.

Turn on the Saute function and bring the jam to a rolling boil, stirring frequently. Let it boil for a few minutes until the mixture thickens.

5. Cool and Store

Turn off the Saute function. Carefully pour the jam into sterilized containers or jars, and allow it to cool completely before sealing. Refrigerate and enjoy!

Tips and Tricks for Perfect Jam

• Use frozen berries without thawing—they release more juice during pressure cooking.

• For a chunkier jam, mash the berries lightly instead of blending.

• Watch closely during the sauté step, as the jam can bubble up quickly once boiling starts.

• Sterilize your jars with boiling water or in the dishwasher to extend freshness.

• Taste before adding cornstarch—adjust sugar or lemon juice based on your preferred tartness.

Variations and Swaps

Want to customize your jam? Here are some creative variations:

• Spiced Berry Jam: Add a pinch of cinnamon, nutmeg, or ginger for a warming twist.

• Citrus Zing: Replace lemon juice with orange juice and zest for a different citrus note.

• Low Sugar Option: Reduce sugar to ½ cup and add 1 tablespoon of chia seeds to thicken the jam naturally.

• Vanilla Berry Jam: Add ½ teaspoon of vanilla extract during the sauté step for extra depth.

How to Store Your Jam

Once cooled, your Instant Pot Mixed Berry Jam can be stored easily:

• Refrigerator: Keep in a clean, airtight jar or container. It will stay fresh for up to 3 weeks.

• Freezer: Yes, you can freeze it! Use freezer-safe jars or silicone molds. Thaw overnight in the fridge when ready to use.

• Not suitable for shelf storage: This is a refrigerator jam and not shelf-stable, so skip the water bath canning method for this one.

Delicious Ways to Enjoy Your Jam

This jam is incredibly versatile. Here are a few serving suggestions:

• Spread it on toasted sourdough, bagels, or croissants

• Stir into Greek yogurt or overnight oats

• Serve as a topping for cheesecake, waffles, or ice cream

• Use as a glaze for pork chops or chicken

• Pair with a cheese board—try it with brie, goat cheese, or sharp cheddar

For drinks, try pairing it with:

• A cup of earl grey or herbal tea

• A fruity rosé wine for brunch

• Sparkling water with a spoonful of jam stirred in for a DIY berry soda

Frequently Asked Questions

Q: Can I double the recipe in the Instant Pot?
A: Yes, just ensure you don’t fill the Instant Pot past the “Max Fill” line. Pressure cook time remains the same.

Q: Is this jam safe for canning?
A: This recipe is intended for refrigeration, not long-term canning. If you’d like to can it, follow tested canning recipes with correct pectin and acidity levels.

Q: Can I use honey or a sugar substitute?
A: Yes, you can use honey, maple syrup, or a granulated sugar substitute. Keep in mind that sweetness and thickening may vary.
