What is Mary Berry’s Rhubarb Jam?

Mary Berry Rhubarb Jam is a fruit preserve made by cooking rhubarb with sugar until thick and glossy. As the rhubarb cooks, it softens and releases natural juices, creating a jam with a vibrant color and slightly tart flavor.

Unlike many other fruits, rhubarb has a strong, tangy taste, which makes the jam refreshing rather than overly sweet. The addition of lemon juice helps balance the flavor and supports the jam’s setting process.

This jam is often served on toast, scones, pastries or used as a filling for cakes and desserts.

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

• Prepare the rhubarb – Wash the rhubarb, trim the ends, and cut it into small pieces.
• Cook the rhubarb first – Place the chopped rhubarb and water in a saucepan and cook over medium heat until the fruit softens.
• Mash lightly – Use a spoon or potato masher to break down the softened rhubarb slightly.
• Add sugar and lemon juice – Stir in the sugar and lemon juice until the sugar dissolves completely.
• Bring to a rolling boil – Increase the heat and boil the mixture rapidly for about 10–15 minutes.
• Test the jam set – Place a spoonful on a chilled plate. If the surface wrinkles when pushed, the jam is ready.
• Remove foam – Skim off any foam from the surface for a smoother jam.
• Fill sterilized jars – Carefully pour the hot jam into sterilized jars using a ladle.
• Seal and cool – Close the jars tightly and allow them to cool completely.

What I Got Wrong (And How I Fixed It)

• Jam too thin – Cooking it a few minutes longer helped it reach the right thickness.
• Adding sugar too early – Cooking the rhubarb first improved the texture.
• Large rhubarb chunks – Cutting smaller pieces created a smoother jam.
• Skipping the set test – Using the chilled plate method ensured proper consistency.

Healthier Version of Mary Berry’s Rhubarb Jam

A lighter version can be made by slightly reducing the sugar to 650–700 g. The jam may be a little softer but will still taste delicious.

You can also mix rhubarb with strawberries or apples, which naturally increase sweetness and reduce the need for extra sugar.

Another option is adding a little honey to replace part of the sugar for a subtle flavor variation.
