Peach + Citrus Marmalade

 

2 lb. peaches peeled, pitted and chopped (about 6 medium)

1 orange peeled + quartered

1 lemon zested, then peeled + roughly chopped

4 tsp. calcium water see step #1

1 tsp. butter to minimize foaming

1 3/4 C. sugar

3 tsp. Pomona’s Pectin mixed with sweetener

 

Before you begin, prepare calcium water. To do this, combine ½ tsp. calcium powder (in the small packet in your box of Pomona’s pectin) with ½ C. water in a small, clear jar with a lid. Shake well. Extra calcium water should be stored in the refrigerator for future use. Wash and rinse jars, lids, and screw bands. Set screw bands aside until ready to use. Place jars in boiling water bath canner with a rack, fill at least 2/3 of the way full with water, and bring to a boil. Boil jars for 10 minutes to sterilize (add 1 additional minute of sterilizing time for every 1000 feet above sea level), then turn down heat and let jars stand in hot water until ready to use. Place lids in water in a small pan, bring to a low simmer, and hold there until ready to use. Rinse the peaches, remove and discard stems and pits, then chop and place in food processor. Process until chopped. Measure 3 C. mashed peaches and place into sauce pan. Rinse citrus. Zest lemon into peaches in the sauce pan. Then roughly chop the lemon and orange and place into food processor. Pulse citrus until it is chopped. Then add to peaches. Add 4 tsp. calcium water to fruit mixture, stir well. Cover saucepan, bring fruit to a boil, and then reduce heat and simmer, still covered, for 5 minutes. In a separate bowl, combine the sweetener and the 3 tsp. pectin powder. Mix well and set aside. Bring the peach mixture to a rolling boil over high heat. Gradually add pectin-sweetener mixture, stirring vigorously between each addition, continue cooking for 1 to 2 minutes to dissolve the pectin while the jam comes back up to a boil. Once the jam returns to a full boil, remove it from the heat. Remove hot jars from canner and fill jars with jam, leaving ¼ inch of headspace. Remove trapped air bubbles, wipe rims with a damp cloth, 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, return the canner to a rolling boil, and boil for 10 minutes. (Add 1 minute additional processing time for every 1000 feet above sea level.) Allow jars to cool undisturbed for 12-24 hours. Confirm that jars have sealed. Remove screw bands from sealed jars, rinse off outside of jars if necessary, label jars, and store for later use.
