Mary Berry Plum Jam Recipe
Enjoy a classic, beautifully simple Mary Berry–style Plum Jam made with just a handful of ingredients. This recipe gives you a rich, ruby-red jam with the perfect balance of sweetness and fruitiness.
Ingredients
- 1 kg plums ripe (halved and stones removed)
- 1 kg granulated sugar
- 150 ml water
- 1 tbsp lemon juice optional, helps with setting
Instructions
Prepare the Plums
- Wash the plums, cut them in half, and remove the stones.
- If some stones are difficult to remove, cook the plums first and take them out later.
Start Cooking
- Place the plum halves and water in a large heavy-bottomed pan.
- Simmer over medium heat for 15 minutes until the plums soften.
Add Sugar
- Add the sugar to the softened plums.
- Stir continuously over low heat until the sugar completely dissolves—avoid boiling at this stage.
Bring to a Boil
- Increase the heat and bring the mixture to a rapid boil.
- Let it boil vigorously for 10–15 minutes, stirring occasionally.
Check the Set
- Test the jam by placing a small spoonful on a chilled plate.
- If it wrinkles when pushed with a finger, it’s ready.
- If not, boil for another 5 minutes and test again.
Jar the Jam
- Turn off the heat and let the jam stand for 5 minutes to settle the fruit.
- Carefully ladle into warm, sterilized jars.
- Seal immediately and let cool completely.
