Perfect for home gardeners, allotment keepers, and jam lovers alike.
? What Is Blackcurrant Jam?
Blackcurrant jam is a traditional fruit preserve made by boiling blackcurrants with sugar until it thickens to a spreadable consistency. It differs from jelly (which is strained) in that it contains the skins and pulp—giving it a stronger flavour, texture, and deep colour.
Why it’s a favourite:
- Naturally high in pectin (no need for jam sugar or additives)
- Bold, sharp flavour that cuts through sweetness
- Pairs beautifully with both sweet and savoury foods
- Lasts for months when properly preserved
? When Are Blackcurrants in Season in the UK?
| Stage | Timeframe |
|---|---|
| Flowering | Late spring (April–May) |
| Harvesting | Late June to August |
| Jam-making best | Early to mid-July |
Pick blackcurrants when they’re fully dark, slightly soft, and easy to detach from the stem.
? Ingredients for Classic Blackcurrant Jam
| Ingredient | Amount |
|---|---|
| Blackcurrants | 1kg (fresh or frozen) |
| Water | 150ml |
| Granulated sugar | 1kg |
| Optional lemon juice | 1 tbsp (helps with set and brightness) |
No need for jam sugar—blackcurrants are naturally high in pectin.
? How to Make Blackcurrant Jam (Step-by-Step)
? Step 1: Sterilise Your Jars
- Wash jars and lids in hot soapy water
- Sterilise in a 140°C oven for 20 minutes
- Place a small plate in the freezer (for testing the set later)
? Step 2: Prepare the Fruit
- Rinse blackcurrants and remove stems or debris
- Place in a large saucepan with the water
- Simmer gently for 10–15 minutes, breaking them up with a spoon
? Step 3: Add Sugar
- Pour in the sugar
- Stir gently over low heat until fully dissolved
- Add lemon juice (optional) for improved set and taste
? Step 4: Boil for Setting Point
- Turn up the heat and bring to a rapid boil
- Boil hard for 5–8 minutes
- Test for set using the wrinkle test:
Wrinkle test:
Drop a spoonful on the chilled plate. After 30 seconds, push gently with your finger—if it wrinkles, your jam is ready. If not, boil for 2 more minutes and test again.
? Step 5: Jar and Seal
- Skim any foam from the surface
- Carefully pour hot jam into warm sterilised jars
- Seal with lids immediately
- Leave to cool fully before labelling
❄️ Can You Use Frozen Blackcurrants?
Absolutely. Frozen blackcurrants make excellent jam.
Tips:
- No need to defrost—use straight from frozen
- Add a few extra minutes to the simmer time
- Slightly increase lemon juice for a brighter taste
? Storage & Shelf Life
| Storage Type | Duration |
|---|---|
| Pantry/cupboard | 12–18 months sealed |
| Fridge (opened) | 3–4 weeks |
| Freezer | Up to 6 months (leave space in jar) |
Use clean spoons to extend the life of opened jars.
