What is Mary Berry Blackcurrant Jam?

Mary Berry Blackcurrant Jam is a classic fruit preserve made by cooking blackcurrants with sugar until thick and glossy.

Blackcurrants naturally contain a high level of pectin, which helps the jam set easily without needing additional pectin. As the berries cook, they soften and release deep-colored juices that create a rich and intensely flavored jam.

The finished jam is bold, fruity, and slightly tart, making it a wonderful contrast to sweet baked goods.

Step-by-Step Guide to Making Mary Berry Blackcurrant Jam

• Prepare the blackcurrants – Wash the berries thoroughly and remove any stems or damaged fruit.
• Cook the fruit first – Place the blackcurrants and water in a large saucepan and cook over medium heat until the fruit softens.

Healthier Version of Mary Berry’s Blackcurrant Jam

You can reduce the sugar slightly by using 650–700 g of sugar instead of 750 g. The jam may be slightly softer but still flavorful.

Another option is replacing part of the sugar with honey, which adds natural sweetness and a subtle floral flavor.

Mixing blackcurrants with apples or raspberries can also balance the tartness and reduce the need for extra sugar.
