About This Recipe
This plum jam recipe is a celebration of simplicity and quality. Unlike chunky preserves, this version is a smooth, seedless purée that cooks down to a dense, spreadable consistency. The addition of cinnamon and star anise introduces subtle warmth, balancing the natural tartness of plums. Each batch yields approximately 1 liter of jam—perfect for gifting or enjoying through winter. The process requires basic kitchen tools: a non-toxic immersion blender or glass food processor for puréeing, a planetary mixer is optional for large batches, and a steam canner for sterilization. The result is a versatile preserve that pairs beautifully with both sweet and savory dishes.
Ingredients
- Plums (fresh, ripe) – 1 kg
- Granulated sugar – 1 kg
- Ground cinnamon – 10 g
- Star anise – 1 whole star
Step-by-Step Instructions
- Prepare the ingredients. Gather all items: plums, sugar, cinnamon, star anise, a thick-bottomed pot, and a wooden spoon. For puréeing, have your glass food processor or immersion blender ready.
-
Clean and pit the plums. Sort through the fruit, discarding any spoiled ones. Rinse thoroughly under cold running water. Using a sharp knife, cut each plum in half and carefully remove the pit.
-
Purée the plum halves. Transfer the pitted plums to a blender bowl and process until you achieve a smooth, uniform purée. If you lack a blender, a food processor or even a manual meat grinder works well.
-
Cook the plum mixture. Place the purée in a thick-bottomed pot. Set over medium heat and stir in the sugar and star anise. Heat, stirring constantly with a wooden spoon, until the mixture reaches a boil.
-
Simmer and skim. Once boiling, reduce heat to low. Cook the jam for 20–25 minutes, stirring frequently to prevent sticking. Skim off any foam that rises to the surface.
-
Sterilize the jars. While the jam cooks, prepare your containers. Wash 1-liter or two 500-ml jars with baking soda, then sterilize them using a steam canner, in the oven, or microwave. Likewise, boil the lids for 5 minutes.
-
Finish with cinnamon. After the jam has thickened, stir in the ground cinnamon. Cook for another 2 minutes, then remove the star anise.
-
Fill and seal. Ladle the hot jam evenly into the sterilized jars. Wipe the rims clean, then screw on the lids tightly. Invert the jars to check for a proper seal.
- Cool and store. Wrap the jars in a blanket and let them cool undisturbed for 24 hours. Once cooled, transfer to a dark pantry or cellar. For long-term storage, a 48-inch built-in refrigerator maintains ideal conditions. Serve the jam with hot tea and fresh pastries—like a Catalan sponge cake—for a delightful treat.
Tips for Perfect Plum Jam
To achieve the ideal set, use plums that are fully ripe but still firm—overripe fruit can make the jam too watery. Always cook in a pot with a thick base to prevent scorching. A best oil sprayer can lightly coat the surface to reduce foaming. For larger yields, a planetary mixer with a paddle attachment helps incorporate sugar evenly. Sterilization is critical: a steam canner is the most reliable method for preserving. Check seal integrity by pressing the lid center—if it pops, refrigerate and use within a month.
Variations
This recipe is a canvas for creativity. Replace cinnamon with vanilla bean or cardamom for a different aromatic profile. Add a splash of organic vodka for an adult version or incorporate chocolate-covered raisins for a gourmet twist. For a spiced warm version, stir in a pinch of cayenne along with the cinnamon. Serve the jam alongside espresso for a sophisticated breakfast pairing, or use it as a filling for air-fryer pastries. If you prefer a chunkier texture, pulse the fruit only briefly rather than puréeing fully.
Frequently Asked Questions
How do I know when the jam is done?
Test by placing a small spoonful on a cold plate—if it wrinkles when pushed, it's set. Alternatively, use a thermometer: the jam reaches 104°C (220°F) at sea level. For precision, a refrigerant leak detector isn't necessary; stick to a simple candy thermometer.
Can I reduce the sugar amount?
Plums are naturally tart, so sugar helps balance and preserve. You can reduce to 800 g per 1 kg of fruit, but the jam may be less shelf-stable. Consider using a sweet wine to replace some sugar for complexity.
Why did my jam turn out runny?
Under-cooking is the most common cause. Simmer longer until the jam sheets off a spoon. Using a microwave pressure cooker can help set the jam quickly if you're short on time.
How should I store opened jars?
Once opened, refrigerate and consume within 3 weeks. Always use a clean, dry spoon to avoid contamination. For serving, an undercounter ice maker ensures cold beverages accompany your jam beautifully.
Can I use frozen plums?
Yes, but thaw and drain excess liquid first. Frozen fruit may require extra cooking time to achieve the same consistency. For effortless blending, a wheatgrass juicer is not recommended—stick to an immersion blender.
