Homemade jam is a simple pleasure that captures the flavour of ripe fruit in a jar. Whether you’re new to preserving or looking for a fuss-free way to make something sweet and spreadable, jam-making is easier than you might think. With just a few ingredients and some basic kitchen tools, you can create a batch of jam that tastes far better than store-bought.
Here’s everything you need to know about making jam at home, plus a tried-and-true strawberry jam recipe.
What You’ll Need
- Fresh or frozen fruit
- Granulated sugar
- Lemon juice (for acidity and to help the jam set)
- Pectin (optional, depending on the fruit and desired texture)
- A large, heavy-bottomed saucepan
- Clean, sterilised glass jars with lids
Tips for Using Fresh vs Frozen Fruit
Fresh fruit: Choose ripe but firm fruit with good flavour. Underripe fruit lacks sweetness, while overripe fruit may result in a dull-tasting jam. Wash thoroughly, remove any stems or pits, and chop as needed.
Frozen fruit: A convenient option when fresh isn’t available. Let the fruit thaw in a colander to release excess water before cooking. Don’t discard the juices — you can include them in your jam for extra flavour. Frozen fruit may take longer to thicken, so extend the cooking time slightly.
Easy Strawberry Jam Recipe
Ingredients
- 1 kg fresh or frozen strawberries (hulled and halved)
- 800 g granulated sugar
- 2 tbsp lemon juice
- Optional: 1 sachet (approx. 7 g) powdered pectin for a firmer set
Instructions
- Prepare the fruit: Place the strawberries in a large saucepan. If using frozen berries, allow them to thaw slightly first. Use a potato masher or fork to gently crush the fruit for a smoother texture.
- Add sugar and lemon juice: Stir in the sugar and lemon juice. If using pectin, add it now and mix well. Let the mixture sit for 10–15 minutes to allow the sugar to begin dissolving.
- Cook the jam: Bring the mixture to a boil over medium-high heat, stirring often. Once boiling, reduce the heat slightly and continue to cook for 15–25 minutes, or until the jam thickens. Skim off any foam that forms on top.
- Test for doneness: Spoon a small amount of jam onto a chilled plate and place it in the fridge for 1 minute. Run your finger through the jam — if it wrinkles and doesn’t flood back, it’s ready.
- Jar the jam: Carefully ladle the hot jam into sterilised jars, leaving about 1 cm of space at the top. Wipe the rims clean, seal with lids, and allow to cool at room temperature.
- Store: Once cooled, store in the fridge for immediate use or process the jars in a boiling water bath for 10 minutes if you’d like to keep them in the pantry.
Once you’ve mastered a basic jam like strawberry, the possibilities are endless. Try mixing fruits (like peach and raspberry), adding spices (like cinnamon or vanilla), or adjusting sugar levels to your taste. Homemade jam isn’t just delicious — it’s also a thoughtful gift and a great way to reduce food waste.
Whether you’re spreading it on toast, swirling it into yoghurt, or gifting it to a friend, nothing beats the taste of jam made in your own kitchen.
