Blackberry Jam
Blackberry jam is a classic fruit preserve made with fresh blackberries, jam sugar and a splash of lemon juice. The Thermomix TM7 handles the preserving process with precise temperature control, so the jam sets beautifully without burning. Ideal on toast, in yoghurt or as a homemade gift, capturing late-summer berries all year round.
About this recipe
Blackberry jam with the Thermomix TM7 is one of the most rewarding preserving recipes you can make in an all-in-one kitchen machine. Just three ingredients — fresh blackberries, jam sugar and lemon juice — transform into a glossy, deep-purple preserve with a tangy-sweet flavour that far surpasses anything from a supermarket jar. The TM7 preserving function controls the heat precisely while stirring automatically, so the sugar dissolves evenly and the fruit cooks without catching on the bottom of the mixing bowl. That means no hovering over a hot hob with a wooden spoon. Whether you have picked a bucket of wild blackberries on a late-summer walk or found a bargain at the market, this recipe turns them into jars of jam that keep for months. Serve it on buttered toast at breakfast, swirl it through yoghurt, or spoon it over pancakes for an easy weekend dessert. Homemade jam also makes a lovely, budget-friendly gift when decanted into pretty sterilised jars with a fabric lid and label.
Preparation tips
- Use perfectly ripe but firm blackberries and check them carefully for stalks and small insects before weighing; a quick soak in cold water helps release any hidden debris from the drupelets.
- Sterilise your jam jars and lids thoroughly before filling: wash them in hot soapy water, rinse well and place in a low oven until completely dry so the blackberry jam seals and keeps safely.
- Test the setting point by placing a teaspoon of hot jam on a chilled saucer; if it wrinkles when pushed with your finger after a minute, it is ready. If not, cook a little longer and test again.
Recipe variations
- For a seedless version, pass the cooked blackberry mixture through a fine sieve before potting, pressing with a spatula to extract all the pulp. The result is a silky, smooth jam, though you will lose a little volume.
- For a seasonal twist, replace half of the blackberries with Bramley apples or add a sprig of rosemary during cooking, removing it before potting. Apple adds natural pectin for a firmer set, while rosemary gives a subtle, festive savoury note.
