Yields: 10 – 4oz. Jars
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.
Wondering what calcium water is? Calcium water is a solution of the monocalcium phosphate powder (food-grade rock mineral source) that comes in its own packet with every purchase of Pomona’s Pectin. The Pomona’s Pectin directions tell you how to make calcium water with the calcium powder. Pomona’s Pectin recipes call for calcium water because the pectin is activated by calcium, not by sugar. You can read more about calcium water here.
Wash jars, lids, and bands. Place jars in canner, fill canner 2/3 full with water, bring to a boil. Turn off heat, cover, and keep jars in hot canner water until ready to use. Place lids in water in a small sauce pan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.
Measure sugar or room temperature honey into a bowl. Thoroughly mix pectin powder into sweetener. Set aside.
Fill hot jars to ¼” of top. Wipe rims clean. Screw on 2-piece lids. Put filled jars in boiling water to cover. Boil 10 minutes (add 1 minute more for every 1,000 ft. above sea level). Remove from water. Let jars cool. Check seals; lids should be sucked down.
