Really Fruity Strawberry Jam Recipe
Introduction
This really fruity strawberry jam captures the vibrant sweetness of ripe strawberries, perfect for spreading on toast or adding to desserts. Made with simple ingredients and a straightforward method, it’s an ideal homemade preserve to enjoy all year round.

Ingredients
- 1¼ kg firm, ripe strawberries, hulled and large ones halved
- 1 kg jam sugar (sugar with added pectin)
- Juice of 1 lemon
- Knob of unsalted butter (optional)
Instructions
- Step 1: Layer the strawberries and sugar in a large bowl, finishing with a layer of sugar on top. Cover the bowl and leave it in the fridge for 24 hours to allow the juices to be drawn out.
- Step 2: Place a couple of saucers in the freezer to chill. If after 24 hours the berries haven’t released enough juice, stir gently and leave for a few more hours.
- Step 3: Pour the strawberry mixture into a preserving pan or a large pan with wide, sloping sides. Warm gently to dissolve the remaining sugar, stirring frequently until the sugar is fully dissolved and the mixture begins to bubble.
- Step 4: Add the lemon juice, bring the mixture back to a boil, then boil hard for 10 minutes, stirring occasionally. If a scum forms on the surface, stir in the knob of butter to remove it.
- Step 5: Test the jam by placing a small spoonful onto one of the chilled saucers. Let it cool slightly, then push your finger through the jam. If it wrinkles and doesn’t run back together, the jam is ready.
- Step 6: Allow the jam to cool for about 30 minutes before spooning it into sterilised jars. Seal and label once completely cool.
Tips & Variations
- Sterilise your jars by washing them in hot, soapy water and drying in a low oven, or run them through a hot dishwasher cycle to ensure a safe preserve.
- For a clearer jam, skim off any foam or scum that forms during boiling using the butter method or a spoon.
- Try adding a splash of vanilla or a few crushed mint leaves during the cooking process for a unique flavor twist.
Storage
Store unopened jars in a cool, dark place for up to one year. Once opened, keep the jam refrigerated and consume within a few weeks. Reheat gently if needed, but avoid boiling the jam again after bottling to maintain texture and flavor.

FAQs
Can I use regular sugar instead of jam sugar?
Jam sugar contains added pectin, which helps the jam set properly. If using regular sugar, you may need to add commercial pectin or cook the jam for longer, but results can vary.
Why does my jam need to be tested on a chilled saucer?
Chilling the saucer cools the jam quickly, allowing you to accurately test its setting point. This helps ensure the jam will thicken correctly once cooled in the jar.

Ingredients
Main Ingredients
- 1¼ kg firm, ripe strawberries, hulled and large ones halved
- 1 kg jam sugar (sugar with added pectin)
- Juice of 1 lemon
- Knob of unsalted butter (optional)
Instructions
- Prepare the Fruit: Layer the strawberries and jam sugar in a large bowl, starting and finishing with a layer of sugar. Cover the bowl and leave it to rest for 24 hours to allow the sugar to draw out the juices from the fruit.
- Check Juice Release: After 24 hours, check that the strawberries have released their juice and are surrounded by a syrup. If not, stir gently and leave for a few more hours until the juice appears.
- Dissolve the Sugar: Pour the strawberry mixture into a preserving pan or a large wide, sloping pan. Warm slowly to dissolve any remaining sugar, stirring frequently to prevent sticking.
- Boil the Jam: Once the sugar is dissolved, bring the mixture to a boil. Stir frequently and then add the lemon juice. Return to boil and let it boil hard for 10 minutes, stirring occasionally. If scum forms on the surface, add a knob of unsalted butter to reduce it.
- Test for Setting Point: Remove the pan from heat and place a small amount of jam on a chilled saucer from the freezer. Let it cool slightly and push your finger through the jam; if it wrinkles and parts, the jam is ready.
- Cool and Jar the Jam: Allow the jam to cool for 30 minutes before potting it into sterilised jars. Once cooled completely, seal and label the jars. Store unopened for up to 1 year; refrigerate once opened.
Notes
- Ensure jars are properly sterilised by washing in hot soapy water and drying in a low oven or running through a hot dishwasher cycle before filling.
- Adding a knob of unsalted butter helps reduce scum during boiling for a clearer jam.
- The jam sugar contains added pectin which helps the jam to set without extra gelling agents.
