Chocolate Berry Jam

Chocolate Berry Jam is a low-sugar cooked jam made with Pomona’s Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener. See below for where to buy.

Chris Wilson of LunaGrown Fine Gourmet Jam, who created this wonderful recipe, says: “This jam is great for a romantic picnic. It makes a wonderful pairing with Swiss cheese, a sharp white cheddar, or a feta goat cheese. It can also be accompanied by fresh pears and apples, served with a Cabernet and some brown bread. The flavor of the chocolate will increase as the jam sets, so depending on your palate you might taste only a hint at first.

Yield: about 8 to 10 cups          Chris’s advice: always boil an extra jar!

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 may be stored in the refrigerator for future use.


1 pound blueberries (about 3 cups)
1 pound raspberries (about 3 cups)
It’s okay to mash the berries if you prefer. If you don’t mash, some will break apart and some will remain whole in the cooking process.
2 1/2 cups unsweetened apple juice (About 4-6 apples if juicing your own – Chris prefers Roma.)
4 teaspoons calcium water
2 Tablespoons lemon juice
3 cups sugar, divided
3 teaspoons Pomona’s pectin powder
2-3 Tablespoons organic chocolate flavoring (Chris uses Flavorganics brand.)


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 saucepan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.

2. Pour apple juice into jam pot. Do not skim off foam or strain.

3. Add rinsed fruit to jam pot. Add calcium water and lemon juice and mix well.

4. Measure 1 cup of the sugar into a bowl. Thoroughly mix pectin powder into sugar. Set aside.

5. Bring fruit mixture to a full boil. Skim off foam. Add pectin-sugar mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the jam comes back up to a boil. Skim off foam.

6. Add the remaining 2 cups of sugar, stirring well as you add.

7. Add chocolate flavoring and stir well.

8. When mixture returns to a full boil, remove it from the heat and skim any foam
Important Note: If you have skimmed foam along the way, there should be very little on the top of your batch. If you continue to stir with your ladle once heat is turned off, any foam (jam bubbles) will dissipate on its own.

9. 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.


Since it is that time of year for bees…. Sometimes open jam containers (anything sweet really) attract bees at otherwise fun and elegant functions. Fresh sliced cucumbers (preferably from the Farmer’s Market, not the grocery store) will keep bees at bay. Slice or carve the cucumbers at your intended function, saving the juice as well, and place intermittently on tables or in planters. The scent of the cucumber will keep the bees away. This will not work for heavily perfumed folks.
