Let’s make the best blackcurrant jam you’ve ever tasted—just like grandma used to.
? Ingredients for Blackcurrant Jam
This recipe makes approximately 3–4 medium jars.
✅ You’ll Need:
- 1kg fresh blackcurrants, washed and stalks removed
- 750ml water
- 1kg granulated or preserving sugar
- Optional: squeeze of lemon juice to help set (if using granulated sugar)
Tip: Use freshly picked blackcurrants in July or August for best results—or frozen ones if you’re preserving out of season.
? Method: Step-by-Step Blackcurrant Jam Recipe
Step 1: Prepare Your Jars
Before you begin, sterilise your jam jars:
- Wash in hot, soapy water
- Rinse and place on a baking tray in a low oven (140°C) for 20 minutes
- Alternatively, run through the dishwasher on a hot cycle
Step 2: Simmer the Blackcurrants
Place the blackcurrants and water into a large, heavy-bottomed pan or preserving pan. Bring to a boil, then simmer for 10–15 minutes until the fruit is soft and the skins have burst.
This breaks down the fruit and releases the juices.
Step 3: Add the Sugar
Stir in the sugar until completely dissolved. If using granulated sugar, add 1 tbsp lemon juice to help the jam set.
Once dissolved, bring to a rolling boil and cook for 10–12 minutes, stirring occasionally.
Step 4: Test for the Set Point
To check if your jam is ready:
- Place a small plate in the freezer before you begin
- Spoon a little jam onto the cold plate
- Let it cool for 1 minute, then push it with your finger
- If it wrinkles and holds shape, it’s ready. If not, boil for 2 more minutes and test again
Step 5: Skim and Jar
Once set, remove the jam from the heat. Skim off any scum on the surface using a spoon.
Carefully ladle the hot jam into sterilised jars. Seal with lids while still hot.
Let the jars cool, then label and store in a cool, dark place.
? What Sugar Should I Use for Blackcurrant Jam?
| Sugar Type | Use Case | Notes |
|---|---|---|
| Granulated Sugar | Works well with blackcurrants (high pectin) | Add lemon juice for best results |
| Jam Sugar | Contains added pectin | Speeds up set, good for beginners |
| Caster Sugar | Also works, but dissolves quickly | Can be more expensive, no real advantage |
Top Tip: Blackcurrants are naturally high in pectin, so you don’t need jam sugar—just make sure to cook to the right set point.
? Optional Additions and Flavour Twists
Want to elevate your jam? Try these additions:
- Lemon zest – brightens flavour and helps with setting
- Vanilla pod or extract – adds smooth depth
- Black pepper – enhances berry flavour subtly
- Port or red wine – rich, festive twist
- Apple – bulks out the jam and adds natural sweetness
Stick to small quantities to avoid overpowering the classic taste.
? Can You Use Frozen Blackcurrants?
Yes! Frozen blackcurrants work just as well.
How to adjust the recipe:
- No need to defrost beforehand
- Use the same quantities
- Simmer 5–10 minutes longer in Step 2 to break them down
Freezing may slightly soften the texture, but the taste will be just as intense.
? How to Store Blackcurrant Jam
| Storage Method | Shelf Life |
|---|---|
| In sterilised jars | 1 year (cool, dark cupboard) |
| Once opened (fridge) | 4–6 weeks |
| Frozen (in containers) | Up to 1 year |
For long-term storage, ensure jars are properly sealed and labelled with the date.
