Ground cherry jam is a delightful way to preserve the unique flavor of these small, golden-hued fruits, which offer a sweet yet slightly tart taste reminiscent of a cross between a tomato and a pineapple. This jam balances their natural brightness with sugar and a hint of citrus, making it perfect for spreading on toast, dolloping on yogurt, or gifting to friends. Because ground cherries have a firm texture and a complex flavor, they make a jam that’s both vibrant and refreshingly different.
Ingredients
- 4 cups ground cherries (about 1 pound), husked and rinsed
- 3 cups granulated sugar
- 1/4 cup fresh lemon juice (about 2 lemons)
- 1 teaspoon finely grated lemon zest
- 1/2 teaspoon ground cinnamon (optional)
- 1/4 teaspoon salt
- 1 packet (1.75 oz) fruit pectin (such as Sure-Jell)
Instructions
- Prepare your jars and lids by washing them in hot, soapy water and sterilizing them in boiling water for at least 10 minutes. Keep them hot until ready to use.
- Remove the husks from the ground cherries and rinse the berries thoroughly under cold water. Drain well.
- In a large saucepan or pot, crush the ground cherries slightly using a potato masher or fork to release some juice but leaving some texture.
- Add the lemon juice, lemon zest, and salt to the pan and stir to combine.
- Sprinkle the fruit pectin evenly over the fruit mixture and stir well to dissolve. Let the mixture sit for 5 minutes to allow the pectin to activate.
- Place the pot over medium-high heat and bring the mixture to a full rolling boil, stirring constantly.
- Once boiling, add the sugar all at once. Stir continuously and return to a full rolling boil. Boil hard for exactly 1 minute, then remove from heat.
- If using cinnamon, stir it in now.
- Skim off any foam from the surface with a spoon to ensure a clear jam.
- Carefully ladle the hot jam into the prepared jars, leaving about 1/4 inch headspace. Wipe the rims clean and seal with sterilized lids and rings.
- Process the jars in a boiling water bath for 10 minutes to ensure proper sealing and preservation.
- Remove jars and let them cool undisturbed for 12-24 hours. Check seals before storing.
Tips
- Substitution for pectin: If you prefer a natural set without commercial pectin, increase the cooking time and add a tablespoon of lemon juice. The jam will be less firm but still delicious.
- Choosing ground cherries: Use fully ripe ground cherries with golden-orange skins and a fragrant aroma for the best flavor and natural sweetness.
- Storage: Unopened jars can be stored in a cool, dark place for up to one year. Once opened, refrigerate and consume within 3 weeks.
- Common mistake: Not boiling the jam long enough can cause it not to set. Use a candy thermometer or the plate test (chill a small spoonful on a cold plate; if it wrinkles when pushed, it’s ready).
Serving Suggestions
Ground cherry jam’s bright, tangy sweetness makes it a versatile condiment. Spread it on warm buttered toast or freshly baked biscuits for breakfast. It pairs wonderfully with soft cheeses like brie or goat cheese on a charcuterie board. For a refreshing twist, swirl it into plain yogurt or oatmeal, or use it as a topping for ice cream or pancakes. You can also add a spoonful to cocktails or sparkling water for a fruity boost.
Variations
Experiment with different flavor profiles by adding spices or complementary fruits. Try stirring in a teaspoon of grated fresh ginger or a splash of vanilla extract for warmth. For a berry boost, add 1 cup of fresh raspberries or blueberries during the cooking process. To make a slightly savory jam, include a pinch of chili flakes or black pepper for subtle heat. You can also substitute lime juice for lemon juice to give the jam a zestier edge.
Storage and Reheating
Properly canned ground cherry jam can be stored unopened in a cool, dark pantry for up to 12 months. After opening, keep the jam refrigerated and use within 3 weeks to maintain the best flavor and prevent spoilage. If the jam thickens or crystallizes in the fridge, gently warm it in a saucepan over low heat or microwave in short bursts, stirring occasionally, until it reaches a spreadable consistency. Avoid overheating, which can degrade the fresh flavors.
Frequently Asked Questions
- Can I use frozen ground cherries to make jam?
- Yes, frozen ground cherries can be used, but thaw them completely and drain excess liquid before cooking. The texture may be softer, so expect a slightly different consistency, but the flavor remains excellent.
- How do I know when the jam is done and will set properly?
- The jam reaches setting point when it thickens and wrinkles during the plate test. Boiling with pectin for at least 1 minute at a full rolling boil usually ensures proper gel formation. Using a candy thermometer, the jam should reach about 220°F (104°C).
- Is ground cherry jam safe to can using a water bath?
- Yes, ground cherry jam is an acidic fruit preserve and can be safely processed in a boiling water bath canner for 10 minutes to ensure shelf stability and prevent spoilage.
- Can I reduce the sugar in this recipe?
- You can reduce sugar slightly, but sugar helps with preservation, texture, and flavor balance. If lowering sugar, consider using a low-sugar pectin designed for jam and refrigerate the jam rather than shelf-storing it.
- What does ground cherry jam taste like?
- Ground cherry jam has a bright, sweet-tart flavor with hints of pineapple, tomato, and citrus. It’s less sweet than many berry jams and has a complex, slightly tropical taste that’s both refreshing and rich.
- Can I use other types of pectin?
- Yes, you can use powdered or liquid pectin, but adjust the timing and quantities according to the manufacturer’s instructions. Some pectins require mixing with sugar before adding to fruit, so follow the package directions carefully.
Making ground cherry jam is a rewarding way to capture the season’s unique flavors in a jar. With its vibrant taste and versatile uses, it’s sure to become a pantry favorite that adds a special touch to everyday meals and gifts alike.
