Why crab apples earn their place in the kitchen

The wild crab apple is one of the great overlooked hedgerow fruits. Small, hard and mouth-puckeringly sour, it is useless raw — but that fierce acidity and its naturally high pectin content make it the finest fruit in the country for set jellies, and a superb base for chutney and sharp sauces. From late August through to November, hedgerows, field edges and old lane ways across the UK carry fruit in shades of green, yellow and flushed crimson.

Wild crab apples (Malus sylvestris) are usually 2–3cm across, with a short stalk and the same star-shaped core and pips as a dessert apple. Many ornamental crabs planted in parks and gardens are also excellent — often larger and more colourful. Avoid fruit from busy roadside verges where exhaust and spray settle, never pick from protected sites or without the landowner's permission, and always leave plenty behind for blackbirds, fieldfares and redwings.

A good rule of thumb: taste one. If it makes you wince, it will make superb jelly. If it is bland or floury, leave it and move on.

Preparing crab apples for the pan

For jelly, you need do almost nothing. Rinse the fruit, cut out any bruised or rotten patches, and roughly chop — stalks, peel, cores and all. Put them in a heavy pan and add water: about 1.2 litres per 1kg of fruit. Bring to a simmer, then cook gently for 30–40 minutes until the fruit has collapsed into a soft, pale pulp. Mash it with a potato masher, then tip everything into a scalded jelly bag or a large square of muslin suspended over a bowl. Leave it to drip overnight — and resist squeezing, or your jelly will be cloudy.

For chutney and sauce, halve the fruit, remove the blossom end and any grubby bits, and leave the pips whole. Apple pips contain a small amount of amygdalin, so keep them intact rather than blitzing them; the straining or sieving stage removes them anyway.

Crab apple jelly

Measure your strained juice and allow 450g of granulated sugar for every 600ml of juice. Warm the sugar in a low oven while you bring the juice to the boil, then add it and stir until completely dissolved. Boil hard for 8–12 minutes, skimming off any scum, until it reaches 105°C on a jam thermometer or wrinkles when a spoonful is dropped onto a chilled saucer.

This is where crab apple jelly comes alive. Infuse the juice before adding sugar with any of the following:

• A sprig of rosemary and a few black peppercorns, for roast lamb
• Two dried chillies and a thumb of grated ginger
• One star anise and a cinnamon stick
• A handful of fresh mint leaves, strained out after 20 minutes

Pot into sterilised jars — 20 minutes in an oven at 140°C, or a hot wash and a warm drying — and seal immediately. One kilogram of fruit yields roughly four to five 340g jars. The jelly keeps its colour and set for at least a year in a cool, dark cupboard.

Spiced crab apple chutney

Chutney is the best home for larger, more awkward fruit. This makes five to six jars and improves immeasurably after a month in the cupboard.

• 1kg prepared crab apples, roughly chopped
• 500g onions, finely chopped
• 250g sultanas or chopped dates
• 400g demerara sugar
• 500ml cider vinegar
• 1 tsp each ground ginger, allspice and cinnamon
• 1 tsp mustard seeds, a pinch of ground cloves and 1 tsp salt

Put everything in a wide, heavy pan and bring slowly to a simmer, stirring until the sugar dissolves. Cook uncovered for 1½–2 hours, stirring often, until the mixture is thick, glossy and a spoon drawn through leaves a clear channel. Pot into warm sterilised jars, seal, and leave for at least six weeks before opening. It will keep for two to three years.

A quick sharp sauce for pork, duck and game

This is the fastest use for a bag of crab apples and the one I make most often. Simmer 500g chopped crab apples with 100ml water for 15 minutes until collapsing. Add 2 tablespoons of sugar and 1 tablespoon of cider vinegar, cook for another five minutes, then push through a sieve. Season with salt and plenty of black pepper.

For pork, stir in a little chopped sage and a knob of butter. For venison or duck, add a few crushed juniper berries and a splash of port. For sausages, a spoonful of mustard and a pinch of chilli is hard to beat. The sauce keeps for two weeks in the fridge and freezes well in small pots.

Storing your haul and foraging kindly

Label everything with the fruit, the date and any flavourings — a blank jar of dark jelly tells you nothing in February. Keep jelly and chutney in a cool, dark place, and check seals before eating anything from the previous year. Any jar that smells fermented, has a furry top or a bulging lid goes straight into the bin.

Take only what you will use, pick from the outside of the hedge where fruit is cleanest, and leave the highest and most sheltered branches untouched. Crab apples are a lifeline for winter birds, and a hedgerow stripped bare in October is a hedgerow with nothing left to give.
