Description
A vibrant, fruity homemade blackberry jam that brings the taste of sun-ripened berries to your table. Perfect for beginners and jam lovers alike.
Ingredients
Scale
- 4 cups fresh blackberries (or frozen and thawed)
- 1 ½ cups granulated sugar
- 2 tablespoons freshly squeezed lemon juice
- 1 packet (1.75 oz) fruit pectin (e.g., Certo)
- ¼ teaspoon butter (optional)
- ½ teaspoon vanilla extract (optional)
Instructions
- Wash fresh blackberries or thaw if frozen. Lightly crush in a large pot.
- Add sugar and lemon juice. Stir and let sit for 15 minutes to macerate.
- Bring mixture to a rapid boil over medium-high heat, stirring constantly. Add pectin and butter (if using), and boil 1–2 minutes.
- Test for doneness with a plate test. If jam wrinkles when pushed, it’s ready. If not, boil another minute and retest.
- Remove from heat. Stir in vanilla extract (if using).
- Ladle hot jam into sterilized jars, leaving ¼ inch headspace. Wipe rims clean.
- Seal with lids and bands. Process in a boiling water bath for 5–10 minutes or refrigerate and consume within a month.
