🫐 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?

Pick blackcurrants when they’re fully dark, slightly soft, and easy to detach from the stem.

🍳 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

1. Rinse blackcurrants and remove stems or debris
2. Place in a large saucepan with the water
3. Simmer gently for 10–15 minutes, breaking them up with a spoon

🍬 Step 3: Add Sugar

1. Pour in the sugar
2. Stir gently over low heat until fully dissolved
3. Add lemon juice (optional) for improved set and taste

🔥 Step 4: Boil for Setting Point

1. Turn up the heat and bring to a rapid boil
2. Boil hard for 5–8 minutes
3. 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:
