Blueberry Blackberry Jam Recipes

QUICK BLACKBERRY-BLUEBERRY JAM

Steps:

• In a large saucepan, combine all ingredients. Stir with a wooden spoon, and let stand for 2 hours.
• Bring mixture to a boil over medium-high heat. Cook, stirring frequently, for 5 minutes. Reduce heat to medium, and cook, stirring frequently and mashing berries with a potato masher, until mixture thickens, 20 to 45 minutes. Remove from heat, and let cool for 1 hour before transferring to a clean jar. Jam will keep refrigerated for up to 2 weeks.

BLUEBERRY-BLACKBERRY JAM

Steps:

• Inspect 8 half-pint jars for cracks and rings for rust; discard any defective ones. Immerse in simmering water until jam is ready. Wash new, unused lids and rings in warm soapy water.
• Toast the almonds in an ungreased skillet until lightly colored, 3 to 5 minutes. Set aside.
• Place crushed blueberries and blackberries in a large pot and add pectin. Slowly bring to a full rolling boil. Add sugar and lemon juice and stir to dissolve. Return to a full rolling boil for exactly 1 minute, stirring constantly. Skim off any foam with a ladle or a large spoon.
• Remove the pot from the heat. Stir in gin and toasted almonds.
• Ladle jam immediately into the prepared jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any spills. Top with lids and tightly screw on rings.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart. Let rest for 24 hours without moving the jars. Gently press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.

BLACKBERRY JAM CROSTATA

Steps:

• Make the jam: In a medium saucepan, stir together blackberries, blueberries, sugar and lemon verbena, if using. Cook over medium heat, stirring occasionally at first, then more frequently as the mixture starts to bubble and reduce.
• When mixture has reduced and looks syrupy (about 30 minutes total), stir in lemon juice and zest. Taste and add sugar if necessary. (This depends on how sweet your berries were to begin with.) Cook for 3 minutes longer, stirring frequently to prevent burning. When the jam is thickened and shiny but still slightly runnier than you expect jam to be, take it off the heat; it will continue to thicken as it cools.
• Scrape jam into a bowl or heatproof container, stir in vanilla and let cool to room temperature. Taste and stir in a little more lemon juice if the jam seems very sweet. At this point, the cooled jam can be chilled for up to 1 week.
• Make the dough: In a medium bowl, whisk together all-purpose and whole-wheat flours, and set aside. In a second bowl and using an electric mixer, beat butter and sugar until pale and fluffy, about 3 minutes. Beat in egg yolks, lemon zest, vanilla, salt and almond extract until combined, then beat in flour mixture.
• Scoop 1/2 cup of the dough into a bowl or container, cover and chill. Transfer remaining dough to a 9- or 10-inch tart pan and use floured fingers to press evenly into bottom and sides. Chill crust in the refrigerator for at least 20 minutes.
• When ready to bake, heat oven to 350 degrees. Spread jam evenly into crust, then using your fingers, crumble reserved 1/2 cup dough over jam. Sprinkle with almonds and Demerara sugar.
• Bake until golden, 38 to 48 minutes. Let cool completely to room temperature before serving.

EASY SMALL-BATCH BLUEBERRY JAM

Steps:

• Mix blueberries, sugar, lemon juice, and cinnamon in a saucepan; cook, stirring constantly, over medium heat until thickened, about 30 minutes.

LUSCIOUS BLUEBERRY JAM

Steps:

• Rinse five 1-cup plastic or freezer-safe containers and lids with boiling water. Dry thoroughly. Mash blueberries; transfer to a Dutch oven. Add lemon juice; stir in pectin. Bring to a full rolling boil over high heat, stirring constantly., Stir in sugar; return to a full rolling boil. Boil for 1 minute, stirring constantly. Remove from the heat; skim off foam. Ladle into containers and cool to room temperature, about 1 hour. , Cover and let stand overnight or until set, but not longer than 24 hours. Refrigerate for up to 3 weeks or freeze for up to 12 months.

BERRY JAM

Steps:

• Toss berries and sugar together in a large, heavy-bottomed pot. Let sit for at least 15 minutes and up to overnight, periodically tossing to coat and to dissolve the sugar. (This will help coax the juices out of the fruit.)
• Place a small plate in the refrigerator to chill. (You'll use this later.)
• Bring the fruit to a strong simmer over medium heat until the berries burst and the juices start to boil, about 15 minutes. If using a vanilla bean as an add-in, put it in the pot at this point.
• Increase the heat to medium-high. Cook the jam, at first stirring occasionally with a wooden spoon or spatula, then more frequently as the juices thicken. Cook until most of the liquid has evaporated and the fruit has begun to break down, 40 to 50 minutes. How much it breaks down will depend on its type and ripeness: For example, strawberries are likely to retain more of their shape, while raspberries will break down almost entirely.
• As the jam cooks, the liquid will reduce, the sugars thicken and the natural pectins activate. You'll notice the liquid go from a rapid, rolling boil with smaller bubbles to a slow, thick, tarlike boil with larger bubbles: This is the stage at which it's most important to stir constantly along the bottom of the pot to prevent scorching and sticking. (Sugar is heavier than water and will concentrate there, increasing the chance that the fruit will burn.) It's also the stage at which splattering may occur, so take care in stirring.
• Once the jam reaches a slow, thick boil, add lemon juice and continue to cook, stirring constantly until the jam returns to its earlier consistency, about another 5 minutes. To test the consistency, spoon a bit of jam onto the chilled plate, return it to the refrigerator and chill for 2 minutes. Drag your finger through it: It should hold its shape on either side without appearing watery or runny. If it's not there yet, cook a few minutes more. (Note: Some fruit, like strawberries, contain more water and less natural pectin than say, a raspberry. This means the jam will never be quite as thick or gelled, but it will still be delicious).
• Remove from heat, and incorporate any of the add-ins listed (see notes). Pick out vanilla bean if you added it earlier. Divide jam between several 8-ounce canning jars, leaving 1/4-inch head space, and seal immediately. Can the jams (see our How to Make Jam guide for more instruction), or store in the refrigerator, using them within a couple of weeks.

BLUEBERRY-LIME JAM

Steps:

• Combine the blueberries, sugar, lime zest, 3 tablespoons lime juice and the salt in a medium saucepan or Dutch oven. Toss well and let stand until the sugar dissolves and the blueberries begin to release their juices, about 15 minutes.
• Bring the mixture to a rapid simmer over medium-high heat. Reduce the heat to maintain a low simmer; cook, stirring often and skimming off any foam, until the blueberries are tender and the juices thicken, about 35 minutes. Add the remaining 1 tablespoon lime juice. Remove from the heat and let the jam cool to room temperature, stirring occasionally, about 1 hour.
• Transfer the jam to a jar or other airtight container. Refrigerate until cold and fully jelled, 3 to 4 hours. Store in the refrigerator for up to 2 weeks.

CANNED BLUEBERRY JAM

Steps:

• Place blueberries in a food processor; cover and process until blended. Transfer to a stockpot. Stir in the sugar, lemon juice, cinnamon, lemon zest and nutmeg. Bring to a full rolling boil over high heat, stirring constantly. Stir in pectin. Boil for 1 minute, stirring constantly., Remove from the heat; skim off foam. Ladle hot mixture into hot sterilized half-pint jars, leaving 1/4-in. headspace. Remove air bubbles; wipe rims and adjust lids. Process for 10 minutes in a boiling-water canner.

BLACKBERRY JAM

Steps:

• The night before you make your jam, layer the blackberries and sugar together in a very large bowl, then cover and set aside at room temperature. This helps the sugar to start dissolving so you don't run the risk of over-cooking the fruit when you actually begin to make the jam. The next morning, give everything a quick stir, then set aside again until you are ready to start cooking.
• Before you start, put a small saucer in the freezer. Take a preserving pan or a large, wide-based pan (the wider and more open the pan, the faster the jam will be ready, so a preserving pan is really ideal) and tip the berries in, scraping out all the juices and any undissolved sugar. Stir in the lemon juice, then collect all the pips and secure them inside a tea-leaf strainer or piece of muslin before adding them to the pan (cooking the pips along with the fruit extracts the pectin they contain, helping your jam to set).
• Start the blackberries over a low heat until all the sugar is completely dissolved, then bring to the boil and simmer for 5 mins. Turn off the heat and spoon a little hot syrupy jam onto the chilled saucer. Once it's cool, push it with your finger. If it wrinkles a little, it's ready and has reached setting point. If it's too runny to wrinkle, return the pan to the heat and boil in 2 or 3-minute stages, removing the pan from the heat each time you do the saucer check, until the jam wrinkles.
• Skim off any excess scum, then stir in the knob of butter, if you want - this will help to dissolve any remaining scum. Leave the jam for 15 mins before ladling into sterilised jars - this allows the fruit to settle so it doesn't sink to the bottom. The jam will keep in a cool, dark place for at least 6 months. Refrigerate jars once opened.

BLUEBERRY JAM

Steps:

• Put a plate in the freezer for you to test your jam is set later. Sterilise two 500ml jam jars so they are ready to use.
• Put the blueberries, sugar, vanilla and lemon in a large heavy-based saucepan over a medium heat. Crush the blueberries a little with a potato masher. Bring to the boil, then reduce to a simmer and cook for 30 mins. Skim off any skum that has formed on the top with a spoon and discard.
• Test the jam is set by spooning a mound on to your cooled plate. Put in to the fridge for 3 mins. If the jam forms a skin and ripples when you push it with your finger, it's ready. If not, return to the heat for 5 more mins then repeat the test. Do this until you reach setting point.
• Leave the jam to sit for 10 mins off the heat. Ladle into your warm, sterilised jars and seal the lids on top. Leave to cool completely. Will keep for six months unopened in a cool, dry place, or two weeks once opened in the fridge.

BLACKBERRY JAM

Steps:

• Mash blackberries in a saucepan with a potato masher. Stir in sugar until juices form; place about 1 tablespoon blackberry juice in a small bowl and stir in cornstarch. Pour cornstarch mixture into saucepan.
• Bring berries to a boil, stirring often, until jam is thickened, about 15 minutes. Stir in cinnamon and allspice. Remove from heat and allow to cool. Transfer jam to a bowl, cover, and refrigerate until chilled. Stir in lemon juice.

BLUEBERRY JAM WITH LIME

Steps:

• Prepare four 1/2-pint jars: Wash jars, lids and rings in hot, soapy water and rinse well. Place jars in a 200-degree oven until needed. Put lids in a pan of boiling water, and cover until needed.
• Place a rack in the bottom of a large stockpot or canning bath. (Or put down a layer of lid rings.) Add enough water to cover jars by 2 to 3 inches (do not put jars in yet) and bring to a boil, then reduce heat. The water will need to be at about 180 degrees - a whispering boil - when jars are added for processing. Place two small saucers in freezer.
• In a large saucepan, gently heat berries with 1/2 cup water until they burst their skins. Remove pan from heat, let cool slightly, and run berries through the coarse blade of a food mill.
• Return purée to pan. Add sugar, lemon juice and cinnamon stick. Cook at a full boil, stirring constantly, until a gel set is achieved, 8 to 10 minutes; mixture will look jammy. To test, drop a teaspoon of the mixture onto a chilled saucer. Put in freezer for 1 minute. Push your finger through jam. If surface wrinkles, it is ready. (If not, cook a few minutes more and repeat with second saucer.) Discard cinnamon stick. Stir in lime juice and zest.
• Ladle hot jam into jars, leaving 1/4-inch head space to allow contents to expand. Run a skewer or other thin tool around the jars' inside edges to release bubbles or air pockets. Wipe rims clean with a damp paper towel, put flat lids in place, and screw on rings just until tight.
• Using a jar lifter or tongs, lower sealed jars into water bath. Cover and rapidly bring water to a full rolling boil. Once water is boiling, boil jars for 10 more minutes.
• Turn off heat and remove jars from water bath. Place on a cutting board or folded dish towel and leave overnight.
• The next morning, verify that jars have sealed. Remove ring and press on center of lid. If the lid moves, or if the "button" in the center flexes, the seal has failed to set. The jam is still safe to eat, but it is not suitable for shelf storage; put it in the refrigerator and use it first. Store sealed jars in a cool, dark place for up to 1 year. Refrigerate after opening. Info Box
