Description
Enjoy the vibrant taste of summer with this easy-to-make sugar-free blackberry jam. Perfect for those seeking a delicious, guilt-free spread without added sugars.
Ingredients
- 4 cups fresh or frozen blackberries
- 1/2 cup water
- 2 tablespoons fresh lemon juice
- 1/4 cup low-sugar or no-sugar pectin
- 1/2 cup granular erythritol or erythritol-stevia blend (or to taste)
Instructions
- 1. Prepare Blackberries: Wash fresh blackberries. If using frozen, do not thaw. Place berries in a large, heavy-bottomed pot. Lightly mash about half of the berries.
- 2. Simmer Berries: Add water and lemon juice to the pot. Bring to a gentle simmer over medium heat, stirring occasionally, for 5-7 minutes until berries soften and release juices.
- 3. Add Pectin: In a small bowl, whisk pectin with 2 tablespoons of the sweetener. Stir this mixture into the simmering berries.
- 4. Boil and Set: Increase heat to medium-high and bring to a full, rolling boil that cannot be stirred down. Boil vigorously for exactly 1 minute, stirring constantly.
- 5. Test and Sweeten: Remove from heat. Perform a plate test for set (place a spoonful on a chilled plate, push after 1-2 mins; if it wrinkles, it’s set). Stir in remaining sweetener, adjusting to taste.
- 6. Jar Jam: Ladle hot jam into clean, sterilized jars, leaving 1/4 inch headspace. Wipe rims, apply lids and bands. Cool on counter for refrigerator storage, or process in a boiling water canner for 10 minutes for shelf-stable jam.
