Ingredients

Here’s what you’ll need to make this delicious Blackberry Jam:

• Fresh Blackberries: You’ll need fresh, ripe blackberries—sweet and slightly tart.
• Sugar: Granulated sugar is used to help preserve the berries and thicken the jam. You can adjust the sugar depending on how sweet your berries are.
• Lemon Juice: A little lemon juice helps balance the sweetness and acts as a natural preservative, enhancing the flavor.
• Optional (Cinnamon or Vanilla Extract): If you want to add a little extra depth of flavor, a pinch of cinnamon or a splash of vanilla extract can make this jam feel extra special. But the blackberry flavor shines just fine on its own!

Instructions

Let’s get cooking! Making blackberry jam is a lot easier than you might think:

Step 1: Prepare the Berries

Wash the blackberries thoroughly, discarding any stems or leaves. Place them in a large saucepan and mash them lightly with a potato masher or fork. You can leave it a bit chunky if you prefer some texture in your jam.

Step 2: Add Sugar and Lemon Juice

Add the sugar and lemon juice to the mashed berries. Stir everything together and let the mixture sit for about 10-15 minutes. This will help draw out the juices from the blackberries and get everything started.

Step 3: Cook the Jam

Place the saucepan over medium heat and bring the mixture to a simmer. Stir occasionally to prevent the jam from sticking to the bottom of the pan. As it heats up, the berries will break down, and the sugar will dissolve into a syrup.

Step 4: Boil and Thicken

Continue to cook the mixture, stirring frequently, for about 20-30 minutes. The jam will begin to thicken and reduce as the water evaporates. Keep a close eye on it to avoid burning, and don’t be afraid to scrape the sides of the pot to incorporate any sugary syrup that might be sticking there.

Step 5: Test the Jam’s Consistency

To test the jam’s consistency, place a spoonful on a chilled plate. Let it cool for a minute, then run your finger through it. If the jam wrinkles and holds its shape, it’s ready. If it’s still too runny, continue to cook for another 5-10 minutes and test again.

Step 6: Sterilize Jars and Pour the Jam

While your jam is simmering, sterilize your jars by washing them in hot, soapy water and then placing them in a hot oven (around 200°F/93°C) for about 10 minutes. Alternatively, you can place the jars in boiling water for a few minutes. Once the jars are hot, carefully pour the jam into them, leaving a little space at the top. Wipe the rims clean with a cloth before sealing.

Step 7: Let it Set and Store

Let the jars cool to room temperature, and as they cool, you’ll likely hear a satisfying pop as the seals on the lids form. Store the jam in the refrigerator for up to 2-3 weeks, or process the jars for long-term storage (see tips below).

Additional Tips

• For Thicker Jam: If you prefer your jam extra thick, you can cook it a bit longer, but be sure to watch it carefully to avoid burning.
• For Sweeter Jam: Taste the jam as it’s cooking. If it’s too tart for your liking, you can add a little extra sugar until you reach your desired sweetness.
• Preserving Tips: If you want to store your jam long-term, you can process the jars in a boiling water bath for 10 minutes to ensure they’re sealed. This will allow the jam to last for up to a year in a cool, dark place.
• Mix with Other Berries: Feel free to mix in other berries like raspberries or blueberries to create a unique berry blend!
