Sloes, Rosehips and Sweet Chestnuts: Late Autumn Foraging in Norfolk
Blackthorn keeps its fruit long after its leaves have started to drop, and by late October the sloes on a Norfolk field hedge show up from some distance: dusky, blue-black and coated in a pale bloom that rubs off on the fingers. Below them the hips on the dog rose have turned from orange to deep scarlet, and in parkland and older woods the sweet chestnuts are coming down in their spiny cases. These three are the end of the hedgerow year. After them there is little worth picking until the wild garlic comes through in spring.
What is ready at the end of October
Sloes are the fruit of blackthorn, Prunus spinosa, the dense, thorny shrub that makes up long stretches of old field boundaries across Norfolk. They are ready from early October, though they keep on the branch well into November in most years. A ripe sloe is the size of a large blueberry, very dark under its bloom, and so astringent eaten raw that one bite is usually enough to put anyone off for good. That tannic dryness is exactly what makes them useful: it cuts through sugar and gives depth to anything they are steeped in.
Rosehips come from the dog rose, Rosa canina, which scrambles through the same hedges. They ripen from September, but they soften and sweeten later in the season, and by the end of October many are deep red and slightly yielding. Firm, glossy hips with no black patches are the ones to take.
Sweet chestnuts, Castanea sativa, are a different kind of harvest altogether. The tree is not a native, and it is usually said to have been introduced to Britain by the Romans, but it has grown here for so long that it feels like part of the countryside. Old parkland, estate drives and mixed woodland are the likeliest places to find one in Norfolk. The nuts drop through October, and the best of them are found in the first days after a windy night, before squirrels and deer get there.
Telling them from their lookalikes
Sloes are easy to confuse with bullaces and wild plums, which grow in the same hedges and look similar from a distance. The confusion is harmless because all are edible, and bullaces are rounder, larger and usually less sour. The thorns are a good giveaway: blackthorn has long, sharp spines along the twigs that catch on sleeves and skin, and gloves are worth wearing for that reason alone.
Rosehips have very few dangerous lookalikes in a British hedge, although the bright berries of bryony and the red fruit of yew sometimes grow close by, and both are poisonous. Hips sit at the tip of a rose stem with the dried remains of the flower at the end and a few small thorns along the stalk; there is little else in a hedge that looks the same once the plant has been followed back to its leaves.
The chestnut problem is the serious one. Horse chestnut, which gives conkers, is common in the same parks, and its nuts are not edible. The two are not closely related, and once seen side by side they are not hard to separate. Sweet chestnut cases bristle with a mass of fine, sharp spines, like a small hedgehog, and usually hold two or three nuts with one flat side and a little pale tuft at the tip. Horse chestnut cases are thick and leathery with a scattering of short, blunt spikes, and normally hold a single round conker. The leaves settle any doubt: sweet chestnut has long single leaves with saw-toothed edges, while horse chestnut has a fan of five to seven leaflets spreading from one point.
Where picking is allowed and where it is not
Foraging in England sits inside a fairly simple set of rules, and most of them come down to good sense. Collecting wild fruit, nuts and leaves for personal use is generally tolerated where there is public access, such as a footpath or open-access land, but it is not a right to take anything from anywhere. Uprooting any wild plant without the landowner’s permission is an offence under the Wildlife and Countryside Act 1981. Picking to sell is treated very differently from picking for the kitchen. Nature reserves, Sites of Special Scientific Interest and many National Trust and estate properties have their own rules, and some do not allow any collecting at all, so a notice board at the entrance is worth reading before reaching into a hedge.
The Countryside Code published by Natural England is a short read and covers access, livestock, dogs and leaving things as they were found.
Picking manners matter as much as the law. Hedges feed birds and small mammals through the winter, and a forager who strips a bush bare is taking a meal that blackbirds, thrushes and fieldfares rely on. Taking a little from many plants, leaving the higher fruit for wildlife and staying off field margins that are being managed for birds is the decent way to do it.
Roadside hedges are best left alone. Verges collect exhaust and spray, and there are usually better plants a short walk down a quiet footpath.
Sloes in the kitchen
Sloe gin is the best-known use, but sloes do well without alcohol. A sloe syrup, made by simmering the fruit with water until it splits, straining and then sweetening the liquid, keeps in the fridge for weeks and works poured over porridge or plant-based yoghurt, stirred into sparkling water or used to glaze roast roots. Sloes are high in pectin, which also makes them good for jelly. Mixed half and half with chopped cooking apples, they make a dark, sharp, wine-coloured jelly that suits a winter cheeseboard and a nut roast equally well.
The old advice is to pick after the first frost. Cold splits the skins and lets the juice out, and in a mild autumn a day or two in the freezer does the same job, so there is no need to leave ripe fruit hanging into December waiting for the weather. Each sloe should still be pricked or squeezed before steeping or simmering, which is fiddly but makes a real difference to how much colour comes out.
Stoning sloes is a thankless job, and none of the recipes above need it. The stones are strained out after cooking. The BBC Good Food sloe recipes include several syrups and jellies that adapt easily for plant-based cooking.
Rosehip syrup, a wartime habit worth keeping
During the Second World War, schoolchildren and volunteers across Britain collected rosehips by the tonne for a national syrup scheme, because imported citrus was scarce and hips are rich in vitamin C. The syrup outlasted the war and many grandparents still remember it on a spoon.
Making it at home is simple, but one step cannot be skipped. Inside each hip, the seeds are packed in fine hairs that irritate the mouth and throat, and old schoolyard itching powder was made from exactly these. The method is to top and tail the hips, chop them roughly in a food processor, drop them straight into boiling water and simmer for a few minutes before taking the pan off the heat and leaving it to steep. The pulp then goes into a jelly bag or a sieve lined with a double layer of muslin, and the liquid is allowed to drip through without squeezing. Strain it a second time through clean muslin, then return the liquid to the pan, add sugar, boil briefly and bottle it hot in sterilised bottles. The result is a thin, bright, sweet-sharp syrup that keeps in a cool cupboard until opened and then in the fridge.
The thyme tea page covers another hedge-and-garden infusion with a long history in British kitchens.
Roasting and cooking sweet chestnuts
Fresh chestnuts must be scored before roasting. A cross cut through the shell on the rounded side lets steam escape; without it, a chestnut in a hot oven or on a fire bursts with a loud crack and sprays hot shell. Twenty minutes at 200°C is usually enough, and they peel most easily while still warm, wrapped for a few minutes in a clean tea towel. The papery inner skin comes off with the shell if they are peeled straight away and stubbornly if they are left to cool.
Beyond eating them straight from the bag, chestnuts are one of the most useful ingredients in plant-based winter cooking. They bring weight and sweetness to a stuffing, fold well into a mushroom and lentil pie, and blend with stock into a smooth soup with a few sage leaves. Cooked chestnuts freeze well, which is a good reason to roast and peel a large batch now and save a bag for the Christmas cooking in December.
Many of the nuts that fall in Britain are small and thin, especially after a cool summer, and some years they are hardly worth the effort of peeling. Picking only the plump ones and leaving the flat, empty-looking nuts on the ground saves a lot of disappointment at the stove.
A note on blackthorn winter
Blackthorn flowers in early spring, often in March, before its leaves appear, covering hedges in white blossom at a time when little else is in bloom. Country lore links that flowering to a sharp cold snap, and a spell of hard weather around that time is still called a blackthorn winter in parts of England. Whether the cold really follows the blossom more often than it follows anything else is doubtful, but the phrase has survived in farming talk for generations, and it is one of the few weather sayings that most people in rural Norfolk would still recognise.
Making the most of the shorter days
The clocks go back on the last Sunday of October, and the afternoons close in fast after that. Hedgerow picking suits a late morning, when the dew has dried and the light is good enough to see a thorn before it finds a finger. A small bag, a pair of gloves and a pocket knife cover nearly everything, and a stick with a crooked end helps pull a high branch down without breaking it.
For the rest of what is ripe in late autumn, the what’s in season calendar runs through the year, and the journal returns to the kitchen garden in November. If you pick only one thing this autumn, make it a bag of sloes from a footpath hedge: frozen overnight, simmered and strained, they become a bottle of syrup that will still taste of October in February.
Questions
Do sloes really need a frost before picking?
Not strictly. The old advice to wait for the first frost exists because cold splits the tough skins and softens the fruit slightly, which helps the juice come out. Sloes picked ripe in October and frozen for a day or two at home behave in much the same way. The real test is ripeness: the fruit should be blue-black, give a little when squeezed and come away from the twig easily.
How can sweet chestnuts be told apart from conkers?
Sweet chestnut cases are covered in dense, fine, needle-like spines and usually hold two or three flattish nuts with a pointed tuft at the tip. Horse chestnut cases have fewer, thicker, widely spaced spikes and normally hold one round, glossy conker. Conkers are not edible and should never be roasted or eaten. The leaves differ too: sweet chestnut has single long toothed leaves, horse chestnut has a hand of five to seven leaflets.
Is it legal to forage in England?
Picking wild fruit, nuts, leaves and flowers for personal use is generally allowed where there is public access, but it is not a free-for-all. Uprooting any wild plant without the landowner's permission is an offence under the Wildlife and Countryside Act 1981, picking to sell is treated differently from picking to eat, and many nature reserves and protected sites do not allow collecting at all. Following the Countryside Code covers most situations.
Why does rosehip syrup need to be strained twice?
The seeds inside rosehips are wrapped in fine hairs that irritate the mouth and throat. Straining the cooked pulp through a jelly bag or a double layer of muslin, and then straining the liquid a second time through a fresh cloth, removes them. Squeezing the bag pushes hairs through, so it is better to let the juice drip slowly under its own weight.
