Grape Jam Recipes

LOW-SUGAR GRAPE JAM

Steps:

• Start by preparing jars and getting water in the canner heating. You want the canner hot, but not boiling, when the jars are ready to be processed.See full water bath canning instructions here.

OLD FASHIONED GRAPE JAM (NO PECTIN ADDED)

Steps:

• Seed grapes as discussed above by squeezing the grape flesh out of the skin and then cooking the pulp down. Put the pulp through a fine mesh strainer and then re-combine the filtered pulp with the grape skins.
• Add the skins and pulp into a saucepan along with the sugar and cook the mixture until it reaches gel stage, about 10-15 minutes. Experienced jam makers can watch for when the type of bubbles change and take on a glossy look. To be sure, test the consistency on a plate that's kept in the freezer or with a candy thermometer.
• Pour the jam into prepared canning jars, leaving 1/4 inch headspace. Store in the refrigerator for immediate use, or process in a water bath canner for 10 minutes. Turn off the heat and allow the jars to sit in the canner for an additional 5 minutes before removing them to cool on a towel on the counter.
• Allow the jars to rest for 24 to 48 hours to completely gel.

CONCORD GRAPE JAM

Steps:

• Sterilize jars:
• Wash jars, lids, and screw bands in hot, soapy water, then rinse well. Dry screw bands. Put jars on a rack in canner or deep pot and add enough water to cover by 2 inches. Bring to a boil, covered, then boil for 10 minutes. Remove from heat, leaving jars in water. Heat lids in water to cover by 2 inches in a small saucepan until thermometer registers 180°F (do not let boil). Remove from heat, leaving lids in water. Keep the jars and lids submerged in hot water, covered, until ready to use.
• Cook jam:
• Chill 2 small plates (for testing jam).
• Slip skins from grapes and purée skins with 1 cup sugar in a food processor, then transfer to a 4- to 6-quart wide heavy pot. Stir in lemon juice, peeled grapes, and remaining 4 cups sugar and boil over moderate heat, stirring frequently and skimming foam, until pulp is broken down, about 20 minutes. Force jam through food mill set over a large bowl. Discard remaining solids. Return jam to pot and cook at a slow boil, skimming foam occasionally and stirring frequently as mixture thickens to prevent scorching, 35 minutes, then test for doneness.
• To test jam, remove from heat, then drop a teaspoonful on a chilled plate and chill 1 minute. Tilt plate: Jam should remain in a mound and not run. If jam runs, continue cooking at a slow boil, testing every 5 minutes, until done, up to 25 minutes more.
• Seal, process, and store jars:
• Drain jars upside down on a clean kitchen towel 1 minute, then invert. Ladle jam into jars, leaving 1/4 inch of space at top. Wipe off rims of filled jars with a clean damp kitchen towel, then top with lids and firmly screw on screw bands. Put sealed jars on rack in canner or pot and add enough water to cover by 2 inches. Bring to a boil, covered, then boil 10 minutes. With tongs, transfer jars to a towel-lined surface to cool.
• Jars will seal; if you hear a ping, it signals that vacuum formed at the top of cooling preserves has made lid concave. Remember that you may or may not be around to hear that ping (some jars make the sound after you remove them from water, and others in same batch may take a few hours); the important thing is for jars to eventually have concave lids. Preserves will thicken as they cool.
• After jars have cooled 12 to 24 hours, press center of each lid to check that it's concave, then remove screw band and try to lift off lid with your fingertips. If you can't, lid has a good seal. Replace screw band. Put any jars that haven't sealed properly in the refrigerator and use them first.

GRAPE JAM

Steps:

• Remove the skins from the pulp and set them aside.
• Place grape pulp in stainless jelly pot with water.
• Bring to boil and simmer 5 minutes.
• Strain to remove the seeds.
• Chop the skins and add to the cooked pulp.
• Measure out 5 cups of the grape pulp mixture and return the pulp to jelly pot.
• Add sugar and butter.
• Heat on medium heat until sugar is melted, then adjust to high heat.
• Heat and stir to full rolling boil that will not stop.
• Add 1 pouch Certo and return to full rolling boil at high heat.
• Boil exactly one minute stirring constantly.
• Fill jars to 1/8 inch from the top.
• Seal with lids.
• Invert jars for 5 minutes.

GRAPE JELLY

Steps:

• Tip the grapes into a large saucepan set over a low heat, then cover and leave to gently cook for 5 mins until the juices start to run. Take a potato masher or fork and mash up the grapes. Leave to cook for about 10 mins more, mashing every now and again until the grapes are falling apart. Place a clean tea towel or kitchen cloth in a sieve set over a bowl, then pour the grape mixture into this. Let the mixture drip through for at least 1 hr or preferably overnight.
• Measure out the juice (you should have about 600ml) and pour it into a pan along with the sugar and lemon juice. Set the pan over a high heat and bring to the boil. Skimming any scum as it boils, let the mixture bubble until the temperature reaches 105C on a sugar thermometer. If you don't have one, put a small plate in the freezer for 5 mins, then pour a little of the juice onto the cold saucer. After 1 min, run your finger through; if the jam wrinkles slightly, it's ready. Pour the hot jam into a sterilised jar. Will keep unopened for up to 3 months.
