Making Simple Fruit Leather from Soft Fruit

Why Fruit Leather Is Worth the Faff

There comes a point every summer when the soft fruit run out of willing eaters. The raspberries are cropping faster than the children can pick them, the freezer has no room left, and the jam shelf is already groaning. That is the moment to think about fruit leather. It is nothing more than pureed fruit, spread thinly and dried slowly until it turns into a chewy, pliable sheet you can roll up and cut into strips.

What makes it so useful on a smallholding is that it takes the oddments. Bruised strawberries, overripe plums, a handful of gooseberries left at the bottom of the punnet, the last few blackcurrants on the bush — all of it goes into the pan together. There is no setting point to chase, no jars to sterilise, and no need for pectin. If you can make apple sauce, you can make fruit leather.

Choosing and Preparing Your Fruit

Almost any soft fruit works. Raspberries, blackberries, strawberries, blackcurrants, redcurrants, gooseberries, cherries, plums, damsons, apricots and even rhubarb all make excellent leather. Windfall apples are the secret weapon: cook them down into a smooth puree and use them to bulk out low-pectin fruits.

• Strawberries and rhubarb are low in pectin and can dry to a sticky, fragile sheet. Add a tablespoon of lemon juice per 500g of fruit, or mix in up to a third apple puree by volume.
• Seedy fruits such as raspberries and blackberries are fine left as they are, but if you dislike the crunch, push the cooked puree through a sieve.
• Stoned fruits need the stones out before cooking. Damsons and sloes are worth sieving to remove skins and stones.
• Windfalls and bruised fruit should have any badly damaged sections cut away, but soft spots are perfectly good for cooking.

Wash everything, pick over for stalks and leaves, and weigh roughly so you know how much you are dealing with.

Cooking the Puree

Put the prepared fruit in a heavy-based pan with a splash of water — two or three tablespoons is plenty for juicy fruit, a little more for damsons or apples. Cook gently with the lid on until everything has collapsed, stirring now and then to stop it catching. This usually takes 10 to 20 minutes.

Once soft, blitz it smooth with a stick blender or in a jug blender. Now sweeten it. For every 500g of prepared fruit, start with one to two tablespoons of sugar or honey, taste, and add more only if you need it. Too much sugar makes a brittle, sticky leather that never quite dries; too little can make a tart but perfectly pleasant snack. A teaspoon of lemon juice per 500g sharpens the flavour and helps preserve the colour.

Return the puree to the pan and cook it down uncovered for another 10 to 15 minutes, stirring often, until it is thick enough that a spoonful holds its shape rather than running off the spoon. This reduction step is what turns a wet puree into something that will dry in a reasonable time. Let it cool slightly before spreading.

Spreading and Drying

Line your trays with baking parchment — not greaseproof, which will cling. Silicone mats work too, but parchment makes peeling easier. Pour on the puree and spread it with the back of a spoon or an offset palette knife to an even 3mm thickness. Thick patches stay tacky for hours while thin edges go brittle, so take a moment to get it level. Leave a 2cm border around the edge.

You have three options for drying:

• A dehydrator is the easiest. Set it to 55–60°C and dry for 6 to 10 hours.
• A fan oven on its lowest setting, ideally 60°C, with the door propped open with a wooden spoon. This needs 4 to 8 hours and a bit of attention.
• A warm airing cupboard or a sunny windowsill works in a hot, dry spell if you are patient and can bring the trays in at night.

Whichever route you take, the leather is ready when it feels dry to the touch, slightly tacky but not sticky, and peels away from the parchment cleanly in one piece. If it tears wetly, give it another hour. If it cracks when you bend it, you have gone slightly too far — it will still taste good, just crumbly.

Storing, Cutting and Using It

Leave the leather to cool completely on the tray, then peel it off the parchment. Lay it on a fresh sheet, roll it up, and cut the roll into 3cm strips with scissors or a sharp knife. A smear of cornflour on the blade stops things sticking.

Store the strips in an airtight jar or tin in a cool, dark cupboard, where they will keep for two to three months. For longer storage, keep them in the fridge for up to six months or freeze for a year. If you spot any mould, discard the whole batch — and next time dry it a little harder or store it cold.

A light dusting of white crystals on the surface is just sugar and is perfectly harmless. Label your jars with the fruit and the date, because raspberry and plum leather look remarkably similar by November.

Flavour Twists and Troubleshooting

Once you have the basic method, it is a lovely thing to play with. A pinch of cinnamon with apple, a little grated ginger with pear, a few chopped mint leaves blitzed into strawberry puree, or a spoonful of vanilla extract in plum all lift the finished leather. You can also combine gluts — blackberry and apple is a classic for good reason.

• Still sticky after hours? The puree was too wet. Cook it down further next time and dry a little longer.
• Cracking and brittle? It has overdried. Rehydrate by laying a damp tea towel over the tray for 20 minutes.
• Stuck fast to the parchment? The layer was too thin or the fruit was very sugary. Freeze the tray for 20 minutes and it should lift.
• Too tart? Sweeten with a little apple puree rather than more sugar, which keeps the texture right.

It is a forgiving, thrifty sort of preserving, and a very good way to turn a glut into something the family will actually eat on a long walk. Start with a single tray and see how you get on.
