Ingredients

  • 1 gal. blackberries
  • 1 gal. sugar

Instructions

  3. Mix well.
  4. Bring to a quick boil and cook rapidly, stirring often. Cook until large bubbles appear.

Tips & Substitutions

For the best flavor, use ripe blackberries and consider adding a tablespoon of lemon juice for extra brightness. If you prefer a less sweet jam, reduce the sugar to 3/4 of the amount of blackberries. Always sterilize your jars before filling them to keep the jam fresh longer. If you want a smoother texture, blend the mixture before boiling.

Serving Suggestions

Storage & Reheating

Store the sealed jars in a cool, dark place for up to a year. Once opened, refrigerate and consume within three weeks. If you have leftovers, consider reheating them gently in a saucepan to soften before spreading or using in recipes.

Frequently Asked Questions

Can I use frozen blackberries for this recipe?

Yes, frozen blackberries can be used, but be sure to thaw and drain them well to avoid excess moisture. This may slightly alter the cooking time, so keep an eye on the consistency while boiling.

How do I know when the jam is done cooking?

The jam is done when it reaches a temperature of 220°F (104°C) or when it passes the 'plate test.' To do this, drop a spoonful on a cold plate; if it holds its shape after cooling, it's ready to be jarred.

Can I make this jam without pectin?

Yes, this recipe doesn't require added pectin as the natural pectin in blackberries helps it set. However, if you prefer a firmer jam, you can add commercial pectin according to package instructions.
