John Harrison has been growing fruit and vegetables for over 30 years, with his wife Val making jams and other preserves from the surplus of that harvest for the same period. In 2004 they started www.allotment.org.uk which is now the largest and most popular website on allotments and vegetable growing. As vegetable growers hate waste, they were soon asked to include recipes for jam making on their website – in no time at all they had compiled enough recipes for a book.
