Can I Use Frozen Blackberries for This Blackberry Jam Recipe?

Absolutely not! You need to use fresh blackberries to get that thick, lush consistency. Frozen berries can be too watery and just won’t do your jam any justice. Stick with the fresh stuff for the best results.

Slow Cooker Blackberry Jam Ingredients

• 2 cups (about 450 grams) of fresh blackberries (not frozen)
• 2 cups (about 400 grams) of granulated sugar
• 2 tbsp (30 ml) of freshly squeezed lime juice
• 1 tsp (5 ml) of freshly ground nutmeg

How To Make Blackberry Jam in Slow Cooker

1. Prepare the Slow Cooker: Begin by placing 2 cups of fresh blackberries into your slow cooker to start the jam-making process.
2. Sweeten the Mix: Carefully measure and add 2 cups of granulated sugar to the slow cooker, adjusting the amount if your blackberries are particularly sweet or tart.
3. Add Lime Juice and Nutmeg: Enhance the flavor by adding 2 tablespoons of freshly squeezed lime juice and 1 teaspoon of freshly ground nutmeg to the mixture.
4. Cook on High: Secure the lid on the slow cooker, set it to high, and let the berries cook for 2 hours, stirring occasionally to ensure even cooking.
5. Reduce to Low Heat: After the initial cooking period, reduce the heat to low and leave the lid slightly ajar, allowing the jam to thicken as it continues to cook.
6. Finish Cooking: Keep the slow cooker on low until the jam reaches a thick, jelly-like consistency, typically about one more hour.
7. Cool and Store: Turn off the slow cooker, let the jam cool, then blend briefly if clumpy. Transfer the cooled jam to a glass jar and refrigerate.

Recipe Tips

• Stirring the Pot: To avoid burning and ensure even cooking, give your jam a good stir every 30 minutes. This little workout will keep it smooth and perfectly thickened.
• Sugar Adjustments: If you find your blackberries a bit tart, don’t hesitate to throw in a little extra sugar. It’s all about balancing that sweet with the sour, like a good dance partner!
• Lime Substitute: Not a fan of lime? Swap it out for lemon juice or even orange juice for a citrus twist that keeps things zesty.
• Testing Consistency: To test if your jam is ready, drop a spoonful on a cold plate; if it gels, it’s jam time! If not, keep cooking, because patience is a virtue and virtue tastes delicious.

Recipe Variations

• Spice It Up: Add a pinch of cinnamon or a dash of vanilla extract to introduce a warm, comforting flavor that hugs your tastebuds.
• Berry Bonanza: Why stop at blackberries? Mix in some raspberries or blueberries for a multi-berry jam extravaganza that’s as colorful as a painter’s palette.
• Chia Seeds Addition: Toss in a tablespoon of chia seeds during the last 30 minutes of cooking for a jam that’s not only tasty but also packed with fiber.
• Reduced Sugar Twist: If you’re watching your sugar intake, reduce the sugar and add a natural sweetener like honey or agave. Just remember, it’s about finding that sweet spot!

What To Serve With Blackberry Jam

Serve your Blackberry Jam with almond flour pancakes, vanilla bean ice cream, or warm brie. Try it atop spiced carrot cake or alongside a charcuterie platter. You can also pair it with homemade almond butter or fresh figs for a delightful contrast.

How To Store Leftover Blackberry Jam

In The Fridge:

Pour the cooled jam into a clean, airtight glass jar and seal it tightly. Store this jar in the refrigerator to keep the jam fresh. Properly stored, the jam will remain good for up to 3 weeks.

In The Freezer:

Blackberry jam does not freeze well due to its sugar and pectin content, which can alter the texture and flavor. It’s best enjoyed fresh or stored in the refrigerator for optimal taste.
