Method

  1. The night before you make your jam, layer the berries and sugar together in a very large bowl, then cover and set aside at room temperature. This helps the sugar to start dissolving so you don't run the risk of over-cooking the fruit when you actually begin to make the jam. The next morning, give everything a quick stir, then set aside again until you are ready to start cooking.
  2. Before you start, put a small saucer in the freezer. Tip the berries, scraping out all juices and any undissolved sugar, into a preserving pan, or a large, wide-based pan (the wider and more open the pan, the faster the jam will be ready so a preserving pan is really ideal). Stir in the lemon juice, then collect all the pips and secure them inside a tea-leaf strainer or piece of muslin before adding to the pan, too (cooking the pips along with the fruit extracts the pectin they contain, helping your jam to set).
  3. Start the berries over a low heat until all the sugar is completely dissolved, then bring to the boil and simmer for 5 mins. Turn off the heat and spoon a little hot syrupy jam onto the chilled saucer. Once cool, push the jam with your finger. If it wrinkles a little, it's ready and has reached setting point. If it is too runny to wrinkle, return the pan to the heat and boil in 2-3 minute stages, removing the pan from the heat each time you do the saucer check, until the jam wrinkles.
  4. Skim off any excess scum, then stir in the knob of butter, if you want - this will help to dissolve any remaining scum. Leave the jam for 15 mins before ladling into sterilised jars (see tip, below) - this allows the fruit to settle so it doesn't sink to the bottom. The jam will keep in a cool, dark place for at least 6 months. Refrigerate jars once opened.

STERILISING YOUR JARS

Wash them in hot, soapy water, then dry in an oven heated to 170C/150C fan/ gas 3 for at least 10 minutes. Always ladle the jam into jars while the jars are still warm.

STORING YOUR JAM

For this recipe, you'll need about 8 jam jars, 8 waxed discs and 8 jar lids or cellophane circles with rubber bands. Remember to label each jar once filled, including the date, and cover with squares or circles of pretty fabric if you're giving them away to friends. You can buy all these from kitchen shops or online from lakeland.com.

VARIATIONS

To make Raspberry & rose jam, use 1.8kg raspberries, leaving out the lemon juice and pips and adding 2-3 tbsp rosewater instead. For Zingy blackcurrant jam, use 1.8kg blackcurrants and add a splash of cassis. For Strawberry & vanilla jam, scrape the seeds from 2 vanilla pods into 1.8kg strawberries as you layer with the sugar, then poke the scraped pods in too, fishing them out before ladling the jam into jars.

    Delicious jam, i just used blackberries and hasnt set properly but then i was very inpatient, think i may return a pot to the pan and try to get it to set a bit better. Still i have had it on my toast the past two mornings and tastes wonderful. Made 6 large jars but my jars quite large.

    I find that jams are more successful if the fruit is dry before using it. It is amazing how much water fruits retain from washing. The jam is not done until enough water is cooked off, so it is best to get rid of excess water first. I find the best way to do that is to lay out paper towels in 3 layers and place the berries individually on the towlels. Leave them for about 10 minutes and you will be amazed at how much water came off of them. It sounds like an annoying step, but it will help with the final product.
