Inky Blue Blueberry Jam Recipes

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.

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

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.

CERTO® BLUEBERRY JAM

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
• Stem and crush blueberries thoroughly, one layer at a time. Measure exactly 4-1/2 cups prepared blueberries into 6- or 8-qt. saucepot. Stir in lemon juice.
• Stir sugar into prepared blueberries in saucepot. Add butter to reduce foaming. Bring to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

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.
