Blueberry Jam

Our classic Blueberry Jam is sure to brighten your day! Be sure to stock up your pantry in the summer months and enjoy this delightful spread all year long…you’ll be glad you did.

Feel free to use other sweeteners that measure like sugar or honey in this recipe. For example, you can use Stevia in the Raw or another Stevia product that measures like sugar, or Splenda that measures like sugar. You can also use a different liquid sweetener, like agave or maple syrup. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener. See below for where to buy.

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.

Blueberry Jam Ingredients:

4 cups mashed blueberries (about 6-8 cups whole blueberries)
1/4 cup lemon juice                                                                                                    2 teaspoons calcium water
½ cup up to 1 cup honey or ¾ cup up to 2 cups sugar
2 teaspoons Pomona’s Pectin powder

Blueberry Jam 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 simmer. Turn off heat and keep lids in hot water until ready to use.

2. Wash, remove any stems/debris and mash blueberries. Measure fruit into sauce pan.

3. Add lemon juice and calcium water and mix well.

4. Measure sugar or room temperature honey into a bowl. Thoroughly mix pectin powder into sweetener. Set aside.

5. Bring fruit mixture to a full boil. Add pectin-sweetener mixture, stirring vigorously 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.

6. 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.

Note: If you’re not sure if your jam is sweet enough, taste it after the pectin is dissolved and jam has come back up to a boil. Not sweet enough? Add more sweetener and stir 1 minute at full boil.
