These non-native nuts are something of a Russian Doll; a smooth, pale-green outer layer covers a further, knobbly shell that gradually hardens. The inner nut resembles two halves of a brain. Fresh walnut kernels are delicious but do not keep for long – shop bought nuts are dried artificially. Walnut trees are surprisingly overlooked in city parks and you might make a great discovery if you take a closer look at your local trees. The big oval leaves are a giveaway.
Damsons are a member of the plum family, frequently found in hedgerows, parks, woodlands and gardens in September and October. The fruit is slightly bigger than a large grape and resembles small plums. Note the distinctive blueish bloom on the skin. Sloes are smaller and harder – the size of a marrowfat pea – and taste very bitter. Damsons are extremely versatile. They are delicious eaten ripe but can be used in jams and crumbles, or even in wines and liquors.
Damson jam Simply weigh your damson haul and then weigh out the same amount of sugar. Add your damsons to a saucepan with a tablespoon of water and heat gently until all the fruit have softened – if you are fussy about stones, you can pick them out at this point. Then add your sugar and make sure it completely dissolves. Boil rapidly for 10 minutes and check whether the jam is at setting point (put a teaspoon of it on a cold plate and slide a finger through it. If it wrinkles, it’s ready). Take off the heat pour into clean jars that you’ve warmed in the oven.
An epic haul of hazelnuts – now pass the crackers. Getty ImagesBorne in clusters, hazelnuts have edible kernels inside hard-shells that are prized by hedgerow foragers; although small mammels often reach them first. Wood mice nibble a circular hole in the nut, squirrels split it neatly in half vertically, bank voles gnaw off the pointed end. If you’re lucky enough to beat the squirrels, the best way to deal with hazelnuts is to carefully shell them, then roast them in a hot oven.
Why roast? Well, it improves the flavor by, give or take, 1,000 per cent. Essentially, it removes the water content making them crunchier and intensifying the nutty flavour. Try 200°C for 15 minutes, checking after 10. The smell of roasting nuts will fill the house and they will turn a perfect shade of brown. And so delicious – especially crushed and sprinkled on ice cream.
Store your nuts in an airtight jar and use within a month.

An acquired taste – some people can eat bowlfuls, others are put off by the shape, texture and strong flavour of these shellfish. October is a good time to forage for these beautiful deep blue molluscs with their orange flesh inside as they are plump after a summer’s rich feeding.
There are two things to watch out for:
1. Make sure you’re foraging on a clean shoreline or beach. Mussels really are what they eat and as filter feeders, this can be a problem. Never forage near a sewage outlet or a beach that has a low environmental rating. Blue Flag beaches are best.
2. Watch the tide. The best mussels are usually found on rocks at the lower point of the tide so be acutely aware of the tide timetable and make sure you have plenty of time to get back to dry land.
Foraging and eating mussels
Some don’ts: don’t pick a whole patch bare of mussels and don’t take anything smaller than the length of your little finger (as a very rough guide) – it won’t be worth it. And don’t take too many full stop. Scrub off the beard and any barnacles and simply steam in seawater for 2-3 minutes. Discard any that don’t open.
