Servings: 56 servings (2 tablespoons each)
Calories: 79kcal
Ingredients
- 6 cups blackberries
- 5 ¼ cups granulated sugar
- 1 (1.75 ounces / 49 grams) package Sure Jell Original Fruit Pectin
Equipment
- Potato Masher
- Mason Jars (7 half-pint jars, or 1 half-pint jar and 6 pint jars)
Instructions
- In a large bowl, use a potato masher to crush the blackberries into small pieces.
- Measure out exactly 3 cups crushed blackberries, then add to a large bowl. (If you have extra blackberries, reserve them for another use.)
- Stir sugar into berries, mixing well. Let the mixture stand for 10 minutes, stirring occasionally.
- After 10 minutes, combine pectin and ¾ cup water in a small pot. Bring mixture to a boil on high heat, stirring constantly. Boil for 1 minute (continuing to stir), then remove from heat.
- Add hot pectin to blackberry mixture, then stir for 3 minutes, or until the sugar is completely dissolved. (This may take longer than 3 minutes.)
- Transfer jam to jars, leaving ½-inch of empty headspace at top. Cover with lids.
- Let jam stand at room temperature for 24 hours, or until set.
- Once jam is set, refrigerate it for up to 3 weeks, or freeze it for up to 1 year. Enjoy!
Notes
Blackberries - Make sure the berries are evenly mashed. You don't want any large chunks of fruit when you're done. I always buy a little extra fruit, just in case I run short.
Avoid Deviating from the Recipe - For the best results, it's important to measure your ingredients accurately, and to follow the directions exactly as written.
Pectin - While there are other brands, for this recipe you need to use Sure Jell Original Premium Fruit Pectin. If you purchased a different brand, follow the directions on the box, and use this recipe as a guide.
Lower Sugar - This recipe won't turn out if you reduce the sugar or use a sugar substitute. For reduced sugar jam, use Sure Jell Low Sugar Pectin instead, and follow the directions on the box.
