Guava Jelly

Guava Jelly is a low-sugar cooked jelly made with Pomona’s Universal Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener.
Servings 5 cups
Ingredients
- 4 cups guava juice about 3 lbs fresh guava
- 3 cups water
- 4 teaspoons calcium water see step #1
- ¼ cup lemon juice bottled if guava is sweet
- ¾ cup up to 2 cups sugar
- 4 teaspoons Pomona’s Pectin powder 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.
- 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.
- Measure 4 cups juice into sauce pan.
- Add calcium water and lemon juice (if needed), and mix well.
- Measure sugar into a bowl. Thoroughly mix pectin powder into sugar. Set aside.
- 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.
- 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.

Can I use frozen guava puree such as Goya?
Can I adjust to replace part of the sugar with Stevia?
Can you use store bought guava nectar or juice to make this recipe?
You sure can, as long as it is all natural with no additional sweeteners.
