Pineapple All-Fruit Jam
Pineapple All-Fruit Jam is an all-fruit cooked jam made with Pomona’s Universal Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener. This recipe was created by Allison Carroll Duffy for Pomona’s Pectin. She says: “It’s delicious swirled into yogurt, or on top of vanilla ice cream.”
Servings 4 cups
Ingredients
- 3 cups peeled crushed fresh pineapple
- 2 teaspoons calcium water see step #1
- 1 cup white grape juice concentrate can be found in your grocer's freezer section
- 2 teaspoons Pomona’s Universal Pectin
Instructions
- Before you begin, prepare calcium water.To do this, combine ½ teaspoon calcium powder (in the small packet in your box of Pomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well.Extra calcium water should be stored in the refrigerator for future use.
- Prepare boiling water canner. Heat jars in simmering water until ready for use. Wash lids and bands and set aside.
- Put the crushed pineapple in a sauce pan and add the calcium water. Set aside.
- In a separate sauce pan, bring the white grape juice concentrate up to a boil. Then, pour it into a blender or food processor, and add the pectin powder. Blend until the pectin powder is fully dissolved–about 1-2 minutes. As the mixture will be hot, be sure to vent the lid while you are blending.
- Put the sauce pan with the pineapple mixture on the stove and bring it up to a rolling boil over high heat. Add the pectin-white grape juice concentrate mixture, then stir vigorously for 1 to 2 minutes, still over the highest heat, to dissolve pectin. Return the jam to a boil, then remove from heat.
- Remove hot jars from canner and fill jars with (marmalade/jam/jelly), leaving ¼ inch of headspace. Remove trapped air bubbles, wipe rims and put on lids and screw bands, tightening bands only to “fingertip tight” (until resistance is met, and then just the tiniest bit more).
- Place jars in the hot water, on the rack inside the canner. (Make sure jars are upright, not touching each other or the sides of the canner, and are covered with at least 1-2 inches of water). Place the lid on the canner, bring the canner to a rolling boil, and boil for 10 minutes. (Add 1 minute additional processing time for every 1000 feet above sea level.)
- Turn off heat and allow canner and jars to sit for 5 minutes. Then, remove jars from canner. Allow jars to cool undisturbed for 12-24 hours. Then, confirm that jars have sealed, then store properly. Eat within 1 year. Lasts 3 weeks once opened.
Unable to find frozen white grape juice. What would be a good substritute
Frozen Apple Concentrate could work too, as long as it does not have any added sweeteners.
Is there a substitute that can be used for grape concentrate?
Apple would be a good substitute for grape concentrate.
Why is frozen concentrated juice added, please?
It is used in this recipe instead of sugar.
