Jumbleberry Jam Recipe
Introduction
Jumbleberry jam is a delightful blend of mixed summer berries that captures the sweetness and tang of the season in every spoonful. This simple recipe creates a luscious, homemade jam perfect for spreading on toast or gifting to friends and family.

Ingredients
- 2 kg mixed summer berries (1 kg halved strawberries, 500 g blackberries, 500 g mixed currants)
- Juice of 2 lemons
- 2 x 1 kg packs jam sugar with pectin
Instructions
- Step 1: Sterilise your jars thoroughly and place a plate in the freezer to chill.
- Step 2: Combine the mixed berries, lemon juice, and jam sugar in a preserving pan. Gently heat the mixture, stirring occasionally with a wooden spoon, until the sugar has dissolved and the fruits are juicy.
- Step 3: Bring the mixture to a rapid boil and continue boiling for 5 minutes.
- Step 4: Remove the pan from the heat and test the jam’s set by dropping a small amount onto the chilled plate. Push your finger through it; it should wrinkle and hold its shape like jam. If not set, boil for an additional 2 minutes and test again. Repeat as needed.
- Step 5: Stir the jam well as it cools to mix in any sediment that may appear on top. Let it cool and settle for 10–15 minutes.
- Step 6: Ladle the jam into the sterilised jars, seal them, and allow to cool completely before storing.
Tips & Variations
- If you prefer a smoother jam, you can lightly crush the berries before cooking to release more juice.
- For a different flavor twist, try adding a teaspoon of cinnamon or vanilla extract during cooking.
- If you want to gift your jam, consider using printable preserves labels to add a personal note.
Storage
Store unopened jars in a cool, dark place for up to one year. Once opened, keep the jam refrigerated and use within a few weeks. Reheat gently if you need to soften before serving.
