Blackberry peach jam is a delightful combination that balances the tartness of blackberries with the sweet, fragrant flavor of ripe peaches. This small batch recipe is perfect for those who want to enjoy fresh, homemade jam without making a large quantity, making it ideal for gifts or personal use.
Ingredients
- 1 cup fresh blackberries (about 5 ounces)
- 1 cup peeled and diced fresh peaches (about 6 ounces)
- 3/4 cup granulated sugar
- 1 tablespoon freshly squeezed lemon juice
- 1/2 teaspoon fruit pectin (powdered)
- 1/4 teaspoon butter (optional, to reduce foaming)
Instructions
- Prepare the fruit: Rinse the blackberries gently under cold water and drain well. Peel the peaches by blanching them in boiling water for 30 seconds, then plunging into ice water; the skins will slip off easily. Dice the peeled peaches into small pieces.
- Macerate the fruit: In a medium saucepan, combine the blackberries, diced peaches, sugar, and lemon juice. Stir gently and let the mixture sit for 10 minutes to macerate, which helps the fruit release its juices.
- Add pectin and cook: Sprinkle the fruit pectin evenly over the fruit mixture and stir well to combine. Add the butter if using. Place the saucepan over medium heat and bring the mixture to a full rolling boil, stirring frequently to prevent sticking and burning.
- Boil and test: Once boiling, maintain a steady boil for 1-2 minutes while stirring constantly. To test if the jam is ready, place a small spoonful on a chilled plate and let it cool for a minute. If it wrinkles when pushed with a finger, the jam has set. If not, boil for another minute and test again.
- Jar the jam: Remove the saucepan from heat. Carefully ladle the hot jam into a clean, sterilized 8-ounce jar, leaving about 1/4 inch of headspace. Wipe the rim clean and seal tightly with a sterilized lid.
- Cool and store: Let the jar cool at room temperature for several hours or overnight. Once cooled, check the seal by pressing the center of the lid; it should not flex up and down. Store unopened jam in a cool, dark place.
Tips
- Substitutions: You can substitute fresh fruit with frozen blackberries and peaches—thaw and drain excess liquid before use to prevent a watery jam.
- Using liquid pectin: If you only have liquid pectin, use 2 tablespoons and add it near the end of the cooking process according to package instructions.
- Preventing foam: Adding a small amount of butter helps reduce foaming during boiling, making the jam clearer and easier to jar.
- Common mistake: Not boiling the jam long enough can result in a runny consistency. Use the plate test to ensure proper setting before removing from heat.
Serving Suggestions
This blackberry peach jam is wonderfully versatile. Spread it on warm toast or English muffins for breakfast, swirl it into plain yogurt or oatmeal for added sweetness, or use it as a glaze for grilled chicken or pork. It also pairs beautifully with soft cheeses like brie or goat cheese on a charcuterie board.
Variations
To customize your jam, try adding fresh herbs such as thyme or rosemary during cooking for an herbal twist. For extra spice, stir in a pinch of cinnamon or ground ginger. You can also swap peaches for nectarines or plums depending on seasonality and preference. For a lower sugar version, use a low-sugar pectin and adjust sugar accordingly, but expect a shorter shelf life.
Storage and Reheating
Unopened, the jam can be stored in a cool, dark pantry for up to 6 months. Once opened, refrigerate and consume within 3 weeks for best flavor and safety. If the jam becomes too firm in the fridge, gently warm it in a saucepan over low heat or in the microwave for a few seconds, stirring occasionally until spreadable. Avoid overheating as this can alter the flavor and texture.
Frequently Asked Questions
Can I use frozen fruit instead of fresh?
Yes, frozen blackberries and peaches work well for jam. Thaw them completely and drain any excess liquid before cooking to avoid a watery final product. You may need to adjust cooking time slightly to reach the desired consistency.
What type of pectin should I use?
Powdered fruit pectin is commonly used for small batch jams and gives you more control over the cooking process. Liquid pectin can also be used but follow the package instructions carefully, as it is usually added later in the cooking process and in different amounts.
How do I know when the jam is done?
The best method is the plate test: place a small amount of hot jam on a chilled plate and let it cool for a minute. Push it with your finger—if it wrinkles and doesn’t flood back, the jam is set. If it remains runny, continue boiling and test again every minute.
Is it safe to can small batches using a water bath?
Yes, blackberry peach jam is high in acid due to the fruit and lemon juice, making it safe for water bath canning. Ensure jars are sterilized and processed for 10 minutes in a boiling water bath to preserve long term. For immediate use, refrigeration is sufficient without canning.
Can I reduce the sugar in this recipe?
Reducing sugar can affect the jam’s ability to set and its shelf life. If you want a lower sugar jam, use a low-sugar pectin designed for such recipes and follow those instructions. Homemade low-sugar jams should be stored in the refrigerator and consumed more quickly.
Why is butter added to jam?
Butter helps reduce foaming during the boiling process, which can make the jam clearer and easier to handle. It doesn’t affect the flavor and is optional but recommended for a smoother cooking experience.
Can I add spices or other flavors?
Absolutely! Adding a cinnamon stick, vanilla bean, or fresh herbs like thyme during cooking can add complexity to your jam. Remove any whole spices before jarring. Start with small amounts so they don’t overpower the fruit flavors.
This small batch blackberry peach jam recipe is a fantastic way to enjoy fresh fruit flavors year-round. With simple ingredients and straightforward steps, it’s approachable even for beginners and makes a lovely homemade gift or pantry staple.
