There is something profoundly satisfying about preserving the fleeting magic of summer berries in a jar. This Blackcurrant and Raspberry Jam—known in Russia as Varenye iz smorodiny i maliny—captures the perfect balance of sweet raspberries and tangy blackcurrants. With a mere handful of ingredients and a simple stovetop method, you can create a vibrant, jewel-toned preserve that elevates everything from morning toast to afternoon tea. Whether you are an experienced canner or a curious newcomer, this recipe promises a taste of old-world charm with every spoonful.
About This Recipe
This jam is a classic Russian preserve, traditionally made in late summer when both berries are at their peak. The combination of fragrant raspberries and tart blackcurrants creates a complex flavor profile that is both refreshing and deeply comforting. Unlike some jams that rely on commercial pectin, this recipe uses the natural pectin found in blackcurrants and a touch of citric acid to achieve a perfect set without clouding the fruit’s bright taste. The process is straightforward, requiring only careful preparation and gentle cooking. For best results, use a high-quality commercial countertop convection oven to sterilize jars, or follow the stovetop method described below. This recipe also pairs beautifully with other summer preserves; explore our Catalan sponge cake for a perfect accompaniment.
Ingredients
- Raspberries – 450 g
- Blackcurrants – 450 g
- Sugar – 600 g
- Citric acid – 4 g
All berries should be fresh, ripe, and free from blemishes. The sugar quantity ensures sweetness while preserving the berries’ natural acidity. Citric acid (or a squeeze of lemon juice) helps stabilize color and flavor. For more on preserving with acid, see our guide on the best steam canner for water-bath methods.
Step-by-Step
-
Prepare the raspberries. Carefully sort through the raspberries, discarding any leaves, stems, or damaged fruit. To clean them without crushing, fill a large bowl with cool water. Place the raspberries in a colander and gently lower it into the water, then lift and let drain. Spread the berries on a clean kitchen towel or paper towels to dry.
-
Clean the blackcurrants. Pick through the blackcurrants, removing any stems, leaves, or spoiled berries. Rinse them thoroughly under cold running water in a colander. Spread both berries on paper towels or a clean cloth in a single layer to air dry completely.
-
Macerate the berries. In a large, heavy-bottomed pot or preserving pan, combine the dried raspberries and blackcurrants. Pour the sugar over the berries and stir gently to coat. Let the mixture sit at room temperature for 1–2 hours, until the berries release their juices. This step is crucial for drawing out natural pectin and flavor. A planetary mixer is not needed here, but a good wooden spoon is essential.
-
Cook the jam. Place the pot on the stove over low heat, stirring occasionally to prevent scorching. Once the sugar dissolves and the mixture comes to a gentle boil, use a slotted spoon to skim off any foam that rises to the surface. This foam can cause cloudiness if left in the jam.
-
Finish cooking. Continue to boil the jam for a few minutes, then reduce the heat to the lowest setting. Cook for another 4–6 minutes, stirring constantly. Add the citric acid and mix well. The jam should thicken slightly—test by placing a small spoonful on a chilled plate; if it wrinkles when pushed, it’s ready. Remove from heat.
-
Jar the preserve. Ladle the hot jam into sterilized glass jars, leaving about 1 cm headspace. Wipe the rims clean, seal with lids, and turn upside down for a few seconds to create a vacuum. Wrap the jars in a thick towel or blanket and let them cool completely at room temperature for 24 hours. Store in a cool, dark place. For optimal sealing, use a steam canner if desired.
Tips for Perfect Jam
Ensure your berries are completely dry before cooking to avoid a watery jam. Use a best oil sprayer (though not for oil) to mist a bit of butter on the surface if foam persists—this reduces bubbles. Always stir with a wooden spoon to prevent metal reactivity. For an even smoother texture, you can use an immersion blender after cooking for a few seconds to break up seeds, but leave it chunky for more character. If you prefer a thicker set, increase cooking time by 2 minutes, but watch carefully; overcooking can cause caramelization. A refrigerant leak detector is not needed, but a kitchen thermometer can help—jam reaches setting point at 105°C (221°F).
Variations
This recipe is endlessly adaptable. Substitute half the raspberries with strawberries for a lighter flavor, or add a vanilla bean (split) during cooking for aromatic depth. For a spiced version, toss in a cinnamon stick or a star anise while simmering—remove before jarring. A dash of organic vodka at the end can enhance preservation and add a subtle kick. You can also reduce sugar to 500 g and use a chocolate-covered raisins as a garnish—though that’s unconventional. For a seedless jam, press the cooked mixture through a fine-mesh sieve before jarring.
Serving Suggestions
Spread this jewel-toned jam on fresh crusty bread, stir into yogurt, or use as a filling for thumbprint cookies. It also makes a luxurious topping for pancakes, waffles, or ice cream. Pair it with a sweet wine for a sophisticated afternoon treat. For an authentic Russian experience, serve it alongside blini or with a dollop of smetana. This jam is also excellent in tea: add a spoonful to hot black tea for a fruity infusion.
FAQ
Why did my jam not set?
The most common reasons are undercooking or insufficient natural pectin. Blackcurrants are naturally high in pectin, but if your berries were too ripe, pectin levels may be lower. Try adding a tablespoon of lemon juice if needed, or cook a little longer. A microwave pressure cooker is not recommended for this, as it may alter texture.
Can I use frozen berries?
Yes, but thaw them completely and drain any excess liquid before macerating. Frozen berries release more water, so you may need to cook the jam 5–10 minutes longer. We recommend using a food processor to chop them quickly if desired.
How long does this jam keep?
If properly sealed and stored in a cool, dark place, it will keep for up to one year. Once opened, refrigerate and consume within three months. For long-term storage, consider using a undercounter ice maker to keep your pantry cool, but a root cellar is ideal.
Can I reduce the sugar?
Yes, but sugar acts as a preservative and affects setting. If you reduce to 400 g, use a commercial pectin to compensate. Alternatively, try a low-sugar pectin blend. A castor oil spritz on the fruit before cooking is not helpful, but a natural pectin booster like grated apple can work.
Why add citric acid?
Citric acid (or lemon juice) helps prevent crystallization, brightens the fruit color, and lowers pH for safer canning. Without it, the jam may become too sweet and cloudy. It also enhances the tartness of blackcurrants. For more on acid in preserving, see our review of the best wall oven microwave combo for even heating.
We hope this blackcurrant and raspberry jam brings a taste of Russian summer into your kitchen. Enjoy the process as much as the result—homemade preserves are a gift of love.
