How to Make the Recipe

Let’s dive into the step-by-step process of making this Wild Black Raspberry Jam. Don’t worry, it’s easier than you think!

Step 1: Prepare the Water Bath

Start by filling a large pot halfway with water and bringing it to a boil. Reduce the heat to maintain a simmer at 180°F. This will be your water bath for processing the jars later.

Step 2: Harvest and Prepare the Berries

Harvest, wash, and drain your berries. If using blackberries, you can skip the crushing step if they’re already soft. For black raspberries, use a potato masher or wooden spoon to crush them until coarse. You’ll need about 4.5 cups of crushed berries with their juice.

Step 3: Combine Ingredients

In a large saucepan, combine the crushed berries, sugar, lemon juice, and vanilla bean paste. Stir well to mix everything together.

Step 4: Bring to a Boil

Place the saucepan over low-medium heat and slowly bring the mixture to a boil, stirring occasionally, until the sugar has dissolved. Once the sugar is dissolved, increase the heat to medium-high and bring the mixture to the gelling point of 220°F, stirring constantly.

Step 5: Fill the Jars

Carefully ladle the hot jam into hot, sterilized mason jars, leaving about 1/4 inch of headspace. Tap gently to remove any bubbles, clean the jar rims as needed, and secure the lids and bands tightly. Repeat until all jars are filled.

Step 6: Process the Jars

Place the sealed jars on the rack in the boiling-water processor, making sure they’re covered by at least an inch of water. Bring the water to a rolling boil, cover, and let boil for 15 minutes. After processing, turn off the heat and let the jars sit for 5 minutes before removing them from the canner.

Step 7: Cool and Store

Let the jars cool at room temperature for 12 hours before labeling and storing them. The jam will keep for up to 6 months in a cool, dark place, or up to a year if stored properly.

Pro Tips for Making the Recipe

Here are a few tips to ensure your Wild Black Raspberry Jam turns out perfectly every time:

  • Use fresh, ripe berries for the best flavor.
  • Don’t skip the lemon juice—it helps balance the sweetness and preserves the color.
  • Invest in a candy thermometer for accurate temperature readings.
  • Always sterilize your jars and utensils to ensure proper canning.

How to Serve

Homemade jam is incredibly versatile! Here are a few ways to enjoy your Wild Black Raspberry Jam:

  • Spread it on toast, biscuits, or English muffins
  • Use it as a topping for yogurt, oatmeal, or ice cream
  • Glaze meats or cheeses for a sweet and savory combination
  • Add it to your favorite smoothie recipe

Make Ahead and Storage

One of the best things about homemade jam is how well it keeps. Store your sealed jars in a cool, dark place for up to a year. Once opened, keep the jar in the refrigerator for up to 6 months. The jam will thicken a bit in the fridge, but it will still taste delicious!
