Raspberry Jam Canned Recipes

Steps:

• 1. Recipe from the book, Blue Ribbon Preserves, by Linda J. Amendt. Before measuring the raspberries, sieve about 3/4 of the crushed fruit to remove the seed or the jam will be mostly seeds. While fresh raspberries usually make the best jam, frozen berries also produce a very good jam. A 12 oz bag of frozen raspberries will yield about 1 1/2 cups of crushed fruit or about 1 cup of seedless pulp. 4 cups crushed, fresh ripe raspberries (6 - 8 pint baskets) 1 tablespoon of strained lemon juice 6 1/2 cups of sugar 1/2 teaspoon unsalted butter 1 (3-ounce) pouch of liquid pectin In an 8-quart pan, combine the raspberries, lemon juice, sugar and butter. Over medium-low heat, stirring constantly, heat the mixture until the sugar is completely dissolved. Increase the heat to medium-high and bring the mixture to a full rolling boil, stirring constantly. Stir in the entire contents of the pectin pouch. Return the mixture to a full rolling boil, stirring constantly. Boil stirring constantly, for 1 minute. Remove the pan from the heat. Skim off any foam. To prevent the jam from separating in the jars, allow the jam to cool 5 minutes before filling the jars. Gently stir the jam every minute or so to distribute the fruit. Ladle the jam into hot jars leaving 1/4 -inch head space. Wipe the jar rims and threads with a clean damp cloth. Cover with hot lids and apply screw rings. Process half-pint jars in a 200°F (93°C) water bath for 10 minutes, pint jars for 15 minutes.

Steps:

• Bring raspberries to a boil in a very large pot. Cook for 4 minutes. Add sugar and lemon juice; stir well. Bring back to a boil, stirring constantly. Cook for another 4 minutes.
• Remove pot from heat and pour jam into sterilized jars, leaving 1/4-inch of space at the top. Seal and transfer jars into a boiling water bath. Make sure jars are covered with at least 1 inch of water; let sit for 5 minutes. Lift jars and let them cool in a draft-free place without touching, 8 hours to overnight.

Steps:

• 1. Place sugar in an ovenproof shallow pan and warm in a 250°F (120°C) oven for 15 minutes. (Warm sugar dissolves better.)
• 2. Place berries in a large stainless steel or enamel saucepan. Bring to a full boil over high heat, mashing berries with a potato masher as they heat. Boil hard for 1 minute, stirring constantly.
• 3. Add warm sugar, return to a boil, and boil until mixture will form a gel (see tips, below), about 5 minutes.
• 4. Ladle into sterilized jars and process as directed for Shorter Time Processing Procedure .
• Tip: To make a small boiling-water canner, tie several screw bands together with string or use a small round cake rack in the bottom of a large covered Dutch oven. Be sure the pan is high enough for 2 inches (5 cm) of water to cover the jars when they are sitting on the rack.

Steps:

• Place a round wire rack in the bottom of a large stockpot. The rack should fit as snugly as possible and should stand 1/2 to 1 inch above the bottom of the pot. Wash five half-pint jars, lids, and screw bands with hot, soapy water; rinse well. Stand the glass jars on the rack, and add the lids; it's not necessary to add the screw bands. Fill the pot with enough water to cover jars by 1 to 2 inches; an additional 1 to 2 inches of space should remain below the rim of the pot so the water doesn't overflow. Cover, and bring the water to a simmer (180 degrees.; let the lids and jars simmer 10 minutes. (The lids and jars can continue to simmer until you're ready to fill them.)
• Using a wooden spoon, lightly crush raspberries in a large, heavy saucepan. Place the pan over high heat, and add pectin and lemon juice. Bring to a boil, stirring constantly. Slowly add sugar, stirring until dissolved. Return the mixture to a boil, and let cook for 1 minute. Remove from the heat.
• Using a jar lifter, remove a jar from the simmering water, and empty the water back into the stockpot. Place the jar on a clean surface, and insert a canning funnel. Using a ladle, pour the jam through the funnel into the jar; fill to within 1/4 inch of the rim. Remove the funnel; wipe the rim with a clean, damp towel. Using the tongs, lift a lid from the hot water; place the lid, sealant side down, on the filled jar. Screw down the band, and tighten firmly, being careful not to force it. With the lifter, stand the filled jar in the simmering water. Repeat with the remaining jam and jars, making sure the jars aren't touching the sides of the pot and are spaced about 1 inch apart.
• Raise the heat to high, cover the stockpot, and bring the water to a boil. Process the jars in the boiling water for 10 minutes. Remove the jars from the water bath with the jar lifter, and transfer them to a wire rack to cool for 24 hours. As the jam cools, a vacuum will form inside the jar, sealing it; you might hear a popping sound. A slight indentation in the lid indicates the vacuum seal; the lid should not flex up and down when pressed firmly with a finger. Store in a cool, dry, dark place for up to 1 year.
