Making cherry jam from frozen cherries is a fantastic way to enjoy the vibrant flavor of cherries year-round. Frozen cherries are often picked at peak ripeness and flash-frozen, preserving their natural sweetness and color, which makes them ideal for jam-making. This recipe guides you through turning those frozen gems into a delicious, spreadable treat with minimal fuss.
Ingredients
- 4 cups frozen pitted cherries (about 20 ounces)
- 3 cups granulated sugar
- 2 tablespoons lemon juice (freshly squeezed preferred)
- 1 packet (1.75 ounces) fruit pectin (powdered, such as Sure-Jell or Ball)
- 1/2 cup water
Instructions
- Prepare cherries: Place the frozen cherries in a large saucepan and allow them to thaw completely over low heat, stirring occasionally to prevent sticking. Once thawed, crush the cherries lightly with a potato masher or fork to release some juice but leave some chunks for texture.
- Add pectin: In a small bowl, combine the fruit pectin with 1/2 cup of water and stir well until fully dissolved. Pour this mixture into the saucepan with the cherries and bring to a boil over medium-high heat, stirring constantly to prevent burning.
- Boil and add sugar: Once boiling, add the granulated sugar all at once. Stir vigorously to dissolve the sugar. Return to a full rolling boil (one that doesn’t stop bubbling when stirred) and boil hard for 1 minute, stirring constantly.
- Add lemon juice: Remove the saucepan from heat and stir in the lemon juice. This brightens the flavor and helps the jam set.
- Test the jam consistency: Place a small plate in the freezer before cooking. Drop a teaspoon of hot jam onto the chilled plate and return it to the freezer for 1 minute. Run your finger through the jam on the plate—if it wrinkles and holds its shape, it’s ready. If not, return the jam to a boil for another minute and test again.
- Jar the jam: While still hot, ladle the jam into sterilized jars, leaving about 1/4 inch headspace. Wipe rims clean, seal with lids, and process in a boiling water bath for 10 minutes if you plan to store long-term. Otherwise, let cool to room temperature and refrigerate.
Tips
- Substitution for pectin: If you prefer a pectin-free jam, you can substitute with 1 cup of finely chopped apples (which contain natural pectin) and increase cooking time to 30-40 minutes to thicken, stirring frequently to avoid burning.
- Using frozen cherries: There’s no need to thaw cherries fully before cooking, but gentle thawing and crushing helps release juices and speeds up the jam-making process.
- Storage advice: Properly canned jars can last up to 1 year in a cool, dark place. Refrigerate after opening and consume within 3 weeks for best flavor.
- Common mistake: Not boiling the mixture long enough after adding sugar can cause the jam to remain runny. Always look for a full rolling boil for at least 1 minute.
Serving Suggestions
Cherry jam is incredibly versatile. Spread it on warm toast or freshly baked scones for a classic breakfast treat. It pairs beautifully with soft cheeses like brie or cream cheese on crackers for an elegant appetizer. Use it as a filling for thumbprint cookies or swirl it into yogurt or oatmeal for a fruity boost. For a savory twist, try glazing roasted pork or chicken with a spoonful of cherry jam mixed with a little balsamic vinegar.
Variations
Customize your cherry jam by adding complementary flavors. Stir in a teaspoon of vanilla extract or a pinch of cinnamon during cooking for warmth and depth. For a boozy touch, add a tablespoon of cherry brandy or kirsch after removing the jam from heat. If you prefer a chunkier texture, reserve some cherries to stir in after cooking. Alternatively, blend the jam briefly with an immersion blender for a smoother spread.
Storage and Reheating
Unopened, properly sealed jars of cherry jam will last up to 12 months stored in a cool, dark pantry. Once opened, keep the jam refrigerated and use within 3 weeks for optimal freshness and safety. If the jam becomes too firm after refrigeration, gently warm it in a small saucepan over low heat or microwave in short bursts, stirring frequently, until it reaches your desired consistency. Avoid overheating to preserve flavor and texture.
Frequently Asked Questions
Can I use frozen cherries without thawing them first?
Yes, you can add frozen cherries directly to the pot, but thawing them first helps release their juices and allows for better control over texture. Gently warming and crushing the cherries before adding pectin and sugar speeds up the cooking process.
What type of pectin should I use?
Powdered fruit pectin is recommended as it dissolves easily and provides consistent results. Liquid pectin can be used, but adjust the timing: add it after boiling the fruit and sugar mixture, then boil for 1 minute. Always follow the package instructions for best results.
How do I know when the jam is set?
The standard test is the chilled plate method: drop a spoonful of hot jam on a cold plate, chill for a minute, then run your finger through it. If the surface wrinkles and the jam holds its shape, it’s ready. If it’s still runny, continue boiling and test again every minute.
Can I reduce the sugar in this recipe?
Reducing sugar will affect the jam’s ability to set and its shelf life. You can experiment with less sugar, but expect a softer set and shorter storage time. For low-sugar or sugar-free versions, consider using pectin specifically designed for low-sugar preserves and follow that product’s instructions.
Is it necessary to process jam jars in a water bath?
For long-term storage at room temperature, yes, processing jars in a boiling water bath for 10 minutes ensures a proper seal and reduces the risk of spoilage. If you plan to consume the jam within a few weeks and keep it refrigerated, this step can be skipped.
Can I add other fruits to this cherry jam?
Absolutely! Cherries pair well with strawberries, raspberries, or blueberries. Adjust sugar and pectin amounts accordingly since different fruits have varying pectin levels. Maintain the total fruit quantity similar to the recipe for consistent texture.
Making cherry jam with frozen cherries is a rewarding way to capture the essence of summer fruit anytime. With a few simple ingredients and straightforward steps, you can enjoy homemade cherry preserves that brighten breakfasts, desserts, and savory dishes alike.
