Preserving Autumn Fruit into Jams and Chutneys

A hedgerow harvest worth bottling

There is a particular satisfaction in standing at the kitchen window in late September, watching rain slide down the glass while a pan of blackberries and apples mutters on the hob. The hedgerows have done their work; now it is your turn. A few hours of stirring in autumn buys you jars that will lift a January breakfast or a cold plate of cheese long after the last leaf has fallen.

Preserving is not difficult, but it does punish guesswork. Get the fruit, the acid and the setting point right, and you will be rewarded with a set that holds on the spoon and a flavour that tastes of the season rather than simply of sugar.

Choosing fruit: pectin, acid and ripeness

Almost anything you can pick in a British autumn will make a preserve of some sort, but it helps to know what each fruit brings. Pectin is the natural gelling agent, and levels vary enormously.

High pectin: crab apples, cooking apples, damsons, plums, quince, sloes and under-ripe blackberries.
Low pectin: raspberries, strawberries, elderberries, ripe blackberries, pears and rosehips.

Under-ripe fruit always contains more pectin than fruit left to soften on the branch, which is why a handful of firm blackberries helps a soft-set jam firm up. Acid does similar work, so add a tablespoon of lemon juice per kilogram of low-acid fruit. It sharpens the flavour and encourages the set. Never rely on sugar alone to do the job.

Finding the setting point

Jam sets at around 104.5°C, and a sugar thermometer gives you confidence, but the saucer test is the one to trust when your pan is bubbling and you need a decision.

Chill two or three small saucers in the freezer before you begin.
When the jam looks thick and the bubbles have turned glassy and slow, take the pan off the heat and drop a teaspoonful onto a cold saucer.
Wait a minute, then push it with your finger. If it wrinkles and holds, it is ready. If it runs, return the pan to the heat for two more minutes and test again.

Always remove the pan from the heat while you test, otherwise you will overshoot. Over-boiled jam tastes of caramel and sets like a wine gum. If that happens, stir in a little warm water and a squeeze of lemon to loosen it before potting.

Flavour pairings that earn their shelf space

The best preserves taste deliberate rather than merely sweet. These combinations have earned their place in many a country kitchen.

Blackberry and apple with a cinnamon stick and a few cloves — the classic autumn set, good on toast or stirred through yoghurt.
Damson and star anise, cooked slowly with a little orange zest. Superb with roast pork or sharp cheese.
Crab apple and chilli, fragrant with ginger. A spoonful transforms a cheese toastie or a plate of cold ham.
Rosehip and orange, strained overnight through muslin to remove the irritant hairs, then set with the juice of a lemon.
Green tomato and apple chutney with mustard seed, ginger and a splash of cider vinegar — the answer to a disappointing tomato season.

Sterilising jars: three reliable methods

Clean jars matter more than any other single step. Mould grows on jam potted into a jar still holding a trace of last year's pickle.

Oven: wash jars in hot soapy water, rinse well, stand upside down on a baking tray and heat at 140°C (120°C fan) for 15 minutes. Keep them warm until filling.
Dishwasher: run on the hottest cycle and leave the jars inside until you need them.
Boiling: submerge jars in a large pan of water, boil for 10 minutes, then lift out with tongs and drain on a clean cloth.

Lids need sterilising too. Metal lids take a two-minute dip in boiling water; never put plastic-lined lids in the oven. Fill jars while both jar and preserve are hot, leave 5mm of headspace for jam, press a wax disc onto chutney, then seal. Leave undisturbed for 24 hours and listen for the click of a vacuum as the lid pulls down.

Chutney, patience and the winter larder

Chutney is jam's forgiving cousin. A workable rough ratio is 1kg of prepared fruit and vegetables to 500ml of vinegar and 400g of sugar, with a teaspoon of salt and your spices tied in muslin. Simmer uncovered, stirring often, for one to two hours until a wooden spoon drawn through the mixture leaves a clear channel that fills slowly. Pot hot, disc and lid on, then leave it alone for at least four weeks. Chutney is raw and sharp on the day it is made and mellow by Bonfire Night.

Store everything in a cool, dark cupboard and label each jar with contents and date. Jam keeps its best flavour for a year; chutney improves for months and will happily see you through to the next glut. A shelf of your own preserves is a small, edible record of the year — and a far better use for a wet Saturday than watching the rain.
