The result is a jam that is sweet, slightly tangy, and full of fresh strawberry flavor, perfect for spreading or baking.

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

• Prepare the strawberries – Wash the strawberries, remove the green tops, and cut them into halves.
• Cook the fruit – Place the strawberries and water in a large saucepan and cook over medium heat until the fruit softens.
• Mash lightly – Use a spoon or potato masher to break the strawberries slightly and release their juices.

• Bring to a rolling boil – Increase the heat and allow the mixture to boil rapidly for about 10–15 minutes.
• Test the jam set – Drop a spoonful of jam onto a chilled plate. If it wrinkles when pushed, the jam is ready.

You can also replace part of the sugar with natural sweeteners like honey, which adds a subtle floral flavor.

Combining strawberries with apples or rhubarb can also enhance natural sweetness and reduce the need for added sugar.
