Four easy autumn jam recipes (2024)

Fig and earl grey jam (pictured above)

Prep 5 min
Cook 15 min
Makes 9 x 220g jars

1.5kg ripe figs (I use Turkish ones)
10g loose earl grey tea leaves (with or without cornflowers)
1kg caster sugar
Juice of 1 lemon

Slice the figs in half, put flat-side down on a board and cut into 5mm slices. Put all the fruit in a heavy-based saucepan with the tea leaves and set over a low heat for five minutes. The aim is to release the tea flavours alongside the natural fig juices.

Slowly add the sugar and lemon juice and stir until the sugar has dissolved. Turn the heat up to high and cook for about 10 minutes, checking every so often that the jam is not sticking, until it reaches setting point – 105C/220F on a sugar thermometer.

Pour into warm, sterilised jars and seal immediately. Store in a cool, dark place.


Greengage and pecan jam

Prep 10 min
Cook 15 min
Makes 7 x 220g jars

1.6kg greengages, halved and stoned
150ml water
800g caster sugar
Juice of 1 lemon
150g pecan halves

Put the greengages in a heavy-based saucepan with the water (so that they don’t stick), set over a medium heat and cook for five minutes.

Once they start to break down, slowly add the sugar and lemon juice and bring to a boil.

Meanwhile, roughly chop the pecans into small pieces, but try to keep them slightly chunky so that they add some texture to the finished jam.

Add the pecans to the pan and cook for eight minutes, until the jam reaches setting point – 105C/220F on a sugar thermometer. Pour into warm, sterilised jars and seal immediately. Store in a cool, dark place.

Sadly greengages aren’t available at most grocery shops, but if you keep an eye out you should find some at farmers’ markets or speciality grocers. Try and look out for Reine Claude, which is an early French variety, or Cambridge Gage, which tends to be a darker blue-green.


Roasted yellow peach and fennel jam

Four easy autumn jam recipes (2)

Prep 20 min
Cook 1 hr 10 min
Makes 10 x 220g jars

2 large fennel bulbs with stalks (green fronds reserved), sliced vertically into long, flat pieces
2kg yellow peaches, halved and stoned
150g demerara sugar
900g caster sugar
Juice of 1 lemon

Heat the oven to 130C/265F/gas ½.

Put the fennel slices in an ovenproof dish in a single layer and rest the peach halves on them, cut-side up. Sprinkle with the demerara sugar and roast for about an hour, until the peaches are cooked and starting to colour. Remove from the oven and leave to cool slightly.

Transfer the peaches, including the skins and juices (discarding the fennel pieces), to a heavy-based saucepan and set over a low heat. Tear up any of the green fennel fronds and scatter them over the peaches.

Add the caster sugar and lemon juice, and cook for 10 minutes, until the jam reaches setting point – 105C/220F on a sugar thermometer. Pour into warm, sterilised jars and seal immediately. Store in a cool, dark place.

Greek tomato jam

Four easy autumn jam recipes (3)

Prep 20 min
Cook 30 min
Makes 5 x 220g jars

1.6kg tomatoes
2 cinnamon sticks
650g caster sugar
200ml apple cider vinegar (preferably one that has a mother in it)

To prepare the tomatoes, bring a large saucepan of water to a boil and have a large bowl of iced water ready. Use a small knife to carve a little cross into the base of each tomato.

Drop them into the boiling water for one minute, then remove using a slotted spoon or tongs and immediately put in the iced water. You may need to do this in a few batches, depending on the size of the saucepan. Leave the tomatoes to cool completely in the iced water for five minutes, then drain. Starting from the bottom of the tomato, you will now be able to peel the skins off the flesh.*

Halve and then quarter each skinned tomato and put in a heavy-based saucepan with the cinnamon and cook for about 10 minutes, until the tomatoes start to break down.

Slowly add the sugar and vinegar, and bring to a boil. Cook for 20 minutes, until the jam reaches setting point – 105C/220F on a sugar thermometer. Pour into warm, sterilised jars and seal immediately. Store in a cool, dark place.

* Another way to peel tomatoes is to halve them horizontally and put, cut-side down, in a roasting tin, and slow-roast them in an oven heated to 130C/265F/gas ½ for 30-40 minutes. Don’t add any oil, as this will give the jam an oily finish on top. Peel off the skins and cook as above.

FAQs

What is the best sugar for jam? ›

Coarse-grain white granulated sugar is best for jam-making as it ensures a good clear jam, but fine caster sugar can also be used. The coarse grains dissolve more slowly and evenly, giving a better result. Granulated sugar with added pectin is also available, but it shouldn't be necessary to use this.

Does lemon juice thicken jam? ›

Lack of acidity: Acids like lemon juice help lower the jam mixture's pH, which reacts with the natural or added pectin to help thicken the jam. If a jam recipe doesn't call for lemon juice or lime juice, it could rely on another ingredient, like added pectin, to set the jam.

What is the main ingredients of jam? ›

The process requires just 20 minutes of preparation and four basic ingredients: fruit, sugar, salt, and lemon juice (though you can use lime juice, as well). Stone fruits like apricots or peaches are a classic choice, but berries and cherries are equally tasty.

What happens if I forget to add lemon juice to my jam? ›

If your recipe called for lemon juice and you forgot to put it in, your mixture will not be acid enough for safe canning. You have to open the jars and put the mixture into a sauce pan. (If you made the jam or jelly recently and you carefully remove the lids without damaging them, you can re-use the same lids.)

Why add lemon when making jam? ›

Adding acid in the form of fresh lemon or lime juice is important for two reasons: First, it makes for a more well-balanced jam, returning some of the acidity lost with the addition of sugar. Second, pectin needs acid to properly activate, or firm up.

What happens if you add sugar too early when making jam? ›

It's important to add the jam sugar at the right time. If you add it in too early, the sugar can cause the fruit to break down and become mushy. If added too late, the jam may not set properly.

Do I need pectin if I use jam sugar? ›

Those fruits make gorgeous jams, but the lack of pectin make those fruits less likely to set when cooked to make your favourite sweet spreads. We add pectin to our jam sugar, so it gives those fruits the pectin they need to set perfectly.

Is brown or white sugar better for jam? ›

Can you use brown sugar in jam? You certainly can! you won't find it in a commercial jam as it adds extra flavour, and the course white sugar they use sets firmer and clearer than brown, but in a blueberry jam, which sets very thick with whatever sugar you use so brown sugar is a great choice for a deeper flavour.

Can I use bottled lemon juice in jam making? ›

You can use bottled lemon juice or fresh. However, I personally look to use other complementary juices to certain fruit jams. Rather than rely on lemon juice I would for example use redcurrant juice from fresh redcurrants in a strawberry jam instead, or an acidic type of apple and apple juice in a blackberry jam etc.

What happens if you boil jam too long? ›

If you don't boil it long enough the pectin network will not form properly. Boil it too long you risk not only losing the fresh flavour and colour of the jam but having a jam with the texture of set honey.

How long should I boil jam for? ›

Boil hard for 5-10 mins until the jam has reached 105C on a preserving or digital thermometer, then turn off the heat. If you don't have a thermometer, spoon a little jam onto one of the cold saucers. Leave for 30 secs, then push with your finger; if the jam wrinkles and doesn't flood to fill the gap, it is ready.

Should I stir jam while it's boiling? ›

5. Do Not Stir Once Mixture Is Boiling. Once your jam/marmalade it has reached a rapid rolling boil do not stir it. Stirring it will alter the temperature of the jam/marmalade meaning it will take longer to reach the setting point.

Will jam set without pectin? ›

Making jam without pectin is easy, you just have to cook it longer. This recipe produces a very thick, rich tasting jam, but if you like your jam a bit looser, cook it 5 minutes less than the suggested cooking time.

How long to boil jam before canning? ›

Process jams in a boiling water bath for 5 minutes if jars are pre-sterilized. Clean hot jars that are not pre- sterilized may also be used; in that case, process jams in the boiling water bath for 10 minutes. (Note: The 5- or 10-minute processing time is for altitudes of 0-1000 feet.
