Kumquat Marmalade

Kumquat Marmalade is a low-sugar cooked marmalade made with Pomona’s 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: "If you are not normally a fan of marmalade but are craving a bit of citrus, this is the marmalade to try!"

Servings cups

Ingredients

2 pounds kumquats
2 cups water
¼ cup lemon juice bottled
2 teaspoons calcium water see step #1
1½ cups sugar
3 teaspoons Pomona’s Pectin mixed with sweetener

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.
Thoroughly rinse the kumquats. Then, slice each kumquat width-wise into several thin, quarter-sized rounds (a small, serrated knife works well for this). Remove and discard the seeds as you are working.
Combine the sliced kumquats and the 2 cups of water in a saucepan, cover with a lid, and bring to a boil. Reduce heat and simmer, stirring occasionally, for 15 minutes, then remove from the heat.
Measure 4 cups of the cooked kumquat mixture. If you have extra, save it for another use. Pour the measured amount of the kumquat mixture into a sauce pan. Add lemon juice and calcium water and stir to combine.
In a separate bowl, combine the sugar and the pectin powder. Mix well and set aside.
Bring the kumquat mixture to a rolling boil over high heat. Add the sugar-pectin mixture, then stir vigorously for 1 to 2 minutes, still over the highest heat, to dissolve pectin. Return the mixture to a boil, then remove it from the 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.
