There is a real satisfaction in opening up a jar of homemade pickle, chutney or savoury relish. With so many varieties of vegetables available throughout the year, there is no need to wait for the traditional autumn bounty. Whatever your favourite vegetable, there is a way to preserve it for eating later. Pickling and preserving are time-honoured ways of making the most of the local vegetable stall - it's so easy and we show you how.
