Yield: 4 to 5 cups
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.
Guava Jelly Ingredients
3 lbs fully ripe guava (to make 4 cups guava juice)
3 cups water
4 teaspoons calcium water
¼ cup lemon juice (if guava is sweet)
¾ cup up to 2 cups sugar
4 teaspoons Pomona’s Pectin powder
Guava Jelly Directions
1. 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.
2. Cut thin slices of unpeeled guava and put in sauce pan. Add water. Bring to a boil, turn down heat, and simmer covered for 5 minutes. Mash guava. Pour mashed fruit into a jelly bag and let drip into bowl until dripping stops. Gently squeeze jelly bag for last bit of juice.
3. Measure 4 cups juice into sauce pan.
4. Add calcium water and lemon juice (if needed), and mix well.
5. Measure sugar into a bowl. Thoroughly mix pectin powder into sugar. Set aside.
6. Bring juice mixture to a full boil. Add pectin-sugar mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the jelly comes back up to a boil. Once the jelly returns to a full boil, remove it from the heat.
7. 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. Eat within 1 year. Lasts 3 weeks once opened.
