Can I Use Frozen Raspberries for This Jam Recipe?

Absolutely, you can use frozen raspberries if fresh ones aren’t available. Just make sure to thaw and drain them properly to avoid excess liquid in your jam.

Slow Cooker Raspberry Jam Ingredients

• 3 pints (about 1.5 liters) of fresh raspberries
• ¾ to 1 cup (150 to 200 grams) of granulated sugar, depending on your sweetness preference
• 2 teaspoons (10 ml) of lemon juice

How To Make Slow Cooker Raspberry Jam

1. Prepare Your Raspberries: If you prefer a smoother texture, blend the fresh raspberries in a blender. Alternatively, for a chunkier jam, mash them well with a fork or potato masher.
2. Mix Ingredients in Slow Cooker: Transfer the raspberries, sugar, and lemon juice to a 5-quart or larger slow cooker. Stir well to combine everything.
3. Cook on Low Heat: Cover the slow cooker set it to LOW and cook for 4 to 6 hours. Prop the lid open slightly with a wooden spoon to allow steam to escape. This will help thicken the jam.
4. Stir Regularly: Give the mixture a good stir every hour to ensure the raspberries cook evenly and don’t stick to the bottom.
5. Check the Consistency: After 4 hours, check if the jam has thickened to your liking. Once it reaches the desired consistency, turn off the slow cooker.
6. Store or Preserve: You can now either process the jam in jars using the hot water bath canning method for 10 minutes (increase to 20 minutes if you’re at a high altitude) or spoon it into freezer-safe containers and freeze.

Recipe Tips

• Check Consistency Regularly: To avoid overcooking, check the consistency of your jam frequently after the first three hours; it should be thick but still spreadable.
• Stir to Prevent Sticking: Stir your jam gently every hour to prevent it from sticking to the bottom of your slow cooker, which can result in a burnt taste.
• Add Flavor Twists: Consider throwing in a vanilla bean or a sprinkle of cinnamon during the last hour of cooking to infuse your jam with additional flavors.
• Prepare Jars in Advance: If you plan on canning your jam, have your jars sterilized and warm before the jam finishes cooking; it makes the canning process smoother and safer.

Recipe Variations

• Berry Delight: Mix raspberries with other berries like strawberries or blackberries for a mixed berry jam that bursts with summer flavors.
• Sugar Alternatives: For a healthier option, substitute granulated sugar with honey or maple syrup; you might need to adjust the quantity to achieve your desired sweetness.
• Spice It Up: Add a small amount of chili powder or freshly ground black pepper to create a jam that offers a sweet heat twist, perfect as a meat glaze or on savory sandwiches.
• Chia Seed Thickener: For an added nutritional boost, stir in a tablespoon of chia seeds after cooking; they’ll help thicken the jam while adding fiber and omega-3 fatty acids.

What To Serve With Raspberry Jam

Serve your Raspberry Jam with oatmeal pancakes, Pumpkin Scones, brie in puff pastry, dark chocolate desserts, and yogurt parfaits.

How To Store Leftover Raspberry Jam

In The Fridge:

Transfer your Raspberry Jam into a clean, air-tight glass jar to maximize freshness. Store it in the refrigerator to keep the flavor and texture intact. It will remain fresh and tasty for up to 3 weeks when stored properly.

In The Freezer:

Raspberry Jam can be frozen, extending its shelf life. Spoon the jam into a freezer-safe container, leaving some space at the top as the jam will expand when frozen. This method will keep the jam good for up to a year.
