Identifying Hawthorn Berries and Making Hawthorn Ketchup

Why Hawthorn Deserves a Place in Your Kitchen

Hawthorn is the backbone of the British hedgerow. Crataegus monogyna, the common hawthorn, is the species you will meet most often — the one that froths with white blossom in May and turns up in nearly every field boundary, lane and scrubby verge in the country. It has been used for centuries as a boundary plant, which is why our landscape is so thoroughly knitted together with it.

By September and October, those same bushes are heavy with deep crimson haws. They are tart, faintly apple-like, with a subtle almond or marzipan note from the single stone inside each berry. Raw, they are seedy and slightly astringent, and eating a lot of them raw can have a laxative effect, so they are best cooked. Simmered, strained and spiced, they make a ketchup that is dark, rich and wonderfully sharp — superb with mature Cheddar, cold roast beef, game pies, sausages or a ploughman's lunch.

Identifying Hawthorn Berries with Confidence

Hawthorn identification is pleasingly straightforward once you know what to look for.

• Berries: deep red, roughly 6–10mm across, round to slightly oval, hanging in loose clusters on short stalks.
• The stone: common hawthorn has a single hard stone per berry. Split one open with your thumbnail and check — midland hawthorn (Crataegus laevigata) has two or three, and is also edible, but the single stone is a reassuring confirmation.
• Leaves: deeply lobed and toothed, a bit like a small, coarse parsley leaf. In autumn they may be turning yellow or bronze, and haws often sit alongside them on the same twig.
• Wood and thorns: hard, grey-brown twigs armed with sharp thorns up to 2cm long. Handle with care and gloves.

Do not rely on berries alone. Several hedgerow shrubs have similar red fruit, so always check the leaves and thorns together. Cotoneaster has small oval glossy leaves and no thorns. Rowan has pinnate leaves in pairs along a stem, and its berries are more orange. Pyracantha has glossy evergreen leaves and orange firethorn berries.

One serious warning: yew is deadly. Its berries look like red cups around a green seed, but its leaves are dark evergreen needles, not lobed. If in any doubt at all, leave it alone. Never pick from a plant you cannot identify with total certainty.

Picking Well and Picking Responsibly

Choose berries that are fully coloured, firm and slightly soft to the touch. Avoid anything shrivelled, mouldy or flea-bitten — haws host a fair few insects, so expect to discard a few.

• Pick from clean sites: away from busy roads, and away from verges that may be sprayed or flailed by the council.
• Take no more than a fifth of the berries from any one bush, and leave plenty for the redwings, fieldfares and blackbirds that depend on them through winter.
• Ask permission on private land, and never pick from a hedge you cannot reach safely. Busy lanes and barbed wire are not worth a jar of ketchup.
• Use a basket or bag you can hang, wear gloves, and wash your haul thoroughly at home.

If you have more haws than you can use in a day, freeze them whole. Freezing softens the flesh and makes the pulp far easier to extract.

Hawthorn Ketchup: What You Need

This makes roughly 500–600ml, or about two average bottles.

• 500g hawthorn berries, stalks and leaves removed
• 300ml cider vinegar
• 150ml water
• 150g soft light brown sugar (or caster)
• 1 onion or 2 shallots, roughly chopped
• 2 garlic cloves, peeled
• 20g fresh ginger, sliced
• 1 tsp black peppercorns
• 4 cloves, or a good pinch of ground cloves
• 1 bay leaf
• 1 tsp smoked paprika (optional but excellent)
• A generous pinch of fine salt

Making and Bottling the Ketchup

Rinse the haws and pick them over carefully, discarding any stalks, leaves and damaged fruit.

Tip them into a heavy pan with the vinegar, water, onion, garlic, ginger, peppercorns, cloves, bay leaf and paprika. Bring to a gentle simmer, then cover and cook for 25–30 minutes until the berries have collapsed and the liquid has taken on a deep ruby colour. Mash with a potato masher to help the pulp release.

Strain the mixture through a jelly bag or a fine sieve set over a bowl. Leave it to drip for at least an hour, ideally overnight, then press the pulp firmly with the back of a spoon to extract every last drop. Don't be tempted to squeeze hard through muslin — a little cloudiness is fine, but grit from the stones is not.

Return the strained liquid to a clean pan with the sugar and salt. Simmer gently, stirring, until the sugar dissolves, then reduce for 15–25 minutes until it coats the back of a spoon and has the consistency of a pourable ketchup. It will thicken further as it cools, so stop slightly short of where you want it.

Taste and adjust — a splash more vinegar for sharpness, a little sugar for balance. Pour into sterilised bottles or jars while hot, seal, and label with the date.

Storing and Using Your Hawthorn Ketchup

Unopened, it keeps in a cool, dark cupboard for up to a year. Once opened, keep it in the fridge and use within four to six weeks.

Serve it as you would a good fruit ketchup: alongside a cheeseboard, with cold ham or roast game, stirred into gravies and casseroles, brushed over sausages before roasting, or spooned onto a bacon sandwich. It also makes a thoughtful homemade gift — a taste of the hedgerow, bottled, that costs nothing but a walk and an afternoon.
