Preserving the Hedgerow: How to Make Fruit Leather

There comes a point in late summer when the hedgerows are groaning with fruit. Blackberries, raspberries, wild plums, and rowan berries all seem to ripen at once. If you are a keen forager, you will find yourself with more fruit than you can possibly eat fresh. Jam is the obvious answer, but there is only so much jam you can make, and it takes a lot of sugar. Fruit leather is a different approach. It is essentially a puree of fruit, dried until it becomes a chewy, leathery sheet. It is naturally sweet, intensely fruity, and it keeps for months in an airtight container. It is also a brilliant way to use up fruit that is slightly past its best.

The beauty of fruit leather is its simplicity. You do not need any special equipment, though a food dehydrator makes the process faster and more consistent. You can also use a regular oven on its lowest setting. The principle is the same: spread a thin layer of fruit puree onto a lined tray and dry it until it is no longer sticky. The result is a flexible, rollable sheet of concentrated fruit flavour. It is the perfect snack for a long walk, a lunchbox, or a post-foraging pick-me-up.

Choosing and Preparing Your Fruit

Almost any fruit can be turned into leather, but some work better than others. Berries are ideal because they are high in pectin and have a natural sweetness. Blackberries, raspberries, and wild strawberries are all excellent. Apples and pears can be used, either alone or mixed with berries, but they need to be cooked first to soften them. Wild plums and damsons also work well, though you will need to remove the stones and cook them down. Avoid fruit that is mouldy or rotten, but do not worry about fruit that is a little bruised or overripe. It will all be pureed anyway.

Start by washing your fruit thoroughly. If you are using berries, you can leave them whole. If you are using larger fruit, such as apples or plums, peel and core them, then chop them into chunks. Cook the fruit gently in a saucepan with a splash of water until it is soft and mushy. This is especially important for firmer fruits. Once the fruit is soft, push it through a sieve or blitz it in a blender until you have a smooth puree. If you want a sweeter leather, add a little honey or sugar to taste. You can also add a squeeze of lemon juice, which helps preserve the colour and adds a pleasant tartness.

Drying and Storing Your Leather

To dry the leather in an oven, line a baking tray with parchment paper or a silicone mat. Pour the puree onto the tray and spread it into an even layer, about 3 to 5 millimetres thick. You want it thin enough to dry quickly but thick enough to hold together when peeled. Place the tray in an oven set to its lowest temperature, ideally around 50 to 60 degrees Celsius. Prop the oven door open with a wooden spoon to allow moisture to escape. The drying time will vary depending on the fruit and the thickness of the layer, but it usually takes between 4 and 8 hours.

If you are using a dehydrator, follow the manufacturer's instructions. Spread the puree onto the dehydrator trays and dry at around 55 degrees Celsius until the leather is firm and no longer sticky to the touch. It should be pliable, not brittle. If it cracks when you bend it, it is over-dried. If it is still tacky, it needs more time.

Once the leather is dry, peel it away from the parchment or mat. It should come away easily. If it sticks, it is not quite ready. Cut it into strips and roll them up. You can store the rolls in an airtight jar or a zip-lock bag. They will keep for several months in a cool, dark place. If you want to prevent them from sticking together, you can dust them lightly with cornflour or wrap them in parchment paper. Fruit leather is a wonderful way to capture the taste of summer and carry it with you into the colder months. It is also a great way to get children involved in foraging, as they can help with the picking, the pureeing, and the rolling. Just be warned: it disappears quickly.
