How to make jam
There’s nothing like a row of colourful summer jams to brighten cold winter days. Now is the time to think ahead and get jamming. To qualify as proper jam, the finished product should contain 60% sugar, including the sugars in the fruit.Top tips
- Use fresh, dry, slightly under-ripe fruit. Strawberries and raspberries are best layered with the sugar and left for a couple of hours before cooking. Plums, currants, gooseberries, cherries etc need to be lightly poached before sugar is added.
- Pectin, naturally found in fruit is vital to make your jam set. With low-pectin fruits like strawberries, help them along by either mixing with pectin-rich fruit like gooseberries or by using jam sugar (with added pectin and citric acid).
- Setting point is 104.5°C. You can tell when jam is reaching setting point as the fast, frothy rolling boil will reduce to a slower, more relaxed boil. The tiny air bubbles disappear, the surface looks glossy and the mixture will feel thicker. Undercook rather than overcook – runny jam can be cooked up again.
- To get rid of scum (which is just trapped air) at the end of cooking, stir in the same direction until reduced.
- When potting up, fill your jars to the brimful when the jam is still over 85°C. If using twist-on metal lids, there’s no need to use waxed discs.

Making fruit leathers and cheeses
Leathers are the ultimate children’s lunchbox solution – a lightly sweetened fruit purée is slowly dried in a low oven producing a thin pliable sheet, a bit like leather. A fruit cheese is a solid, sliceable preserve – perfect with cheese.Top tip
- Leave leathers in the oven until they’re completely dry. You can then peel off the baking parchment easily.
Top tips for making liqueurs, syrups and cordials
- Make sure your fruit is perfectly ripe.
- Prick fruit with a needle to help the juices flow.
- Don’t wash the fruit unless vital.

Top tips for making pickles and chutneys
- Remove any air pockets by gently tapping the jars on your work surface.
- Be sure to pack to within 5mm of the top of the jar.
- Seal with vinegar-proof twist-on lids.
Top tips for making jellies
These are clear jams without ‘bits’ in them, made by boiling strained fruit juice with sugar. They’re best made with fruits high in pectin, though if your fruit isn’t, combine with a fruit that is, like apples and gooseberries. To every 600ml of juice, add 450g sugar.
- To speed up the flow of the straining juice, put a small saucer and heavyish weight (for example, a water filled jam jar) on top of the fruit pulp.
