Ingredients

• Fruit: 1 kg fresh blackcurrants (cleaned and stems removed)
• Sweetener: 900 g granulated sugar
• Acid: 2 tbsp fresh lemon juice

Instructions

Step 1

Place a small plate in the freezer (for testing jam set).

Step 2

In a large saucepan, combine blackcurrants and lemon juice. Gently crush some berries with a potato masher to release juices.

Step 3

Add sugar; stir to combine. Let sit for 10 minutes to draw out juices.

Step 4

Place the saucepan over medium heat. Stir until sugar dissolves completely.

Step 5

Increase heat to high; bring the mixture to a rapid boil. Stir frequently to prevent sticking.

Step 6

Boil hard for 10–15 minutes, skimming off any foam. To test setting point, place a drop of jam on the chilled plate. Wait 1 minute, then push gently with your finger—if it wrinkles, the jam is ready.

Step 7

Remove from heat. Let sit for 5 minutes, stirring occasionally to disperse fruit evenly.

Step 8

Ladle hot jam into sterilized jars, leaving 0.5 cm headspace. Seal immediately.

Step 9

Let cool at room temperature, then label and store in a cool, dark place.

Zusatztipps für die Zubereitung

To ensure a successful set, use a large heavy-bottomed saucepan for even heat distribution. A potato masher is the ideal tool for crushing some of the berries to release their natural pectin. Make sure to have a wooden spoon and ladle ready for the rapid boil and jarring process.

Varianten und Anpassungen

For a smoother jam, pass cooked blackcurrants through a sieve before adding sugar to remove skins and seeds. You can also experiment by adding a vanilla pod or a splash of cassis liqueur for an extra layer of flavor. Always check sugar packaging for cross-contamination if severe allergies are present.

Serviervorschläge

Enjoy this jam spread generously on warm toast or swirled into creamy yogurt bowls. For the best quality, remember to refrigerate the jam after opening and consume it within 4 weeks.

Recipe Guide

→ How do I know when the jam is ready?

Test setting point by placing a drop of hot jam on a chilled plate from the freezer. Wait one minute, then push gently with your finger—if the surface wrinkles, the jam has reached proper consistency and is ready to jar.

→ Can I use frozen blackcurrants instead of fresh?

Yes, frozen blackcurrants work perfectly. Thaw them slightly before starting and include any juices released during thawing. You may need to boil for an additional minute or two to reach proper setting point.

→ How long does this preserve keep?

Properly sealed and stored in a cool dark place, unopened jars will keep for up to one year. Once opened, refrigerate and consume within four weeks for best quality and flavor.

→ What's the purpose of lemon juice?

Fresh lemon juice adds brightness and helps the jam set properly. The natural acidity interacts with fruit pectin and sugar, creating the proper gel consistency while enhancing the tangy flavor profile.

→ Can I reduce the amount of sugar?

Sugar is crucial for preservation and setting. Reducing sugar significantly affects shelf life and texture. For lower sugar options, use commercial pectin specifically designed for reduced-sugar preserves.

→ Why let the jam sit before jarring?

Resting for five minutes prevents fruit from floating to the top. This brief cooling period helps distribute berries evenly throughout the jar, ensuring consistent texture in every spoonful.
