Book excerpt: In this new addition to the award-winning collection, River Cottage master preserver Pam Corbin helps you transform the abundance of your garden (and your friends’ and neighbors’ gardens) into everything from jams and jellies to vinegars and sauces. The River Cottage farm, established by British food personality Hugh Fearnley-Whittingstall to promote high-quality, seasonal, and sustainable food, has inspired a television series, restaurants and classes, and a hit series of books. Now, with The River Cottage Preserves Handbook, learn to make everything from simple Strawberry Jam to scrumptious new combinations like Honeyed Hazelnuts, Nasturtium “Capers,” Onion Marmalade, Spiced Brandy Plums, and Elixir of Sage, plus a pantryful of butters, curds, pickles, chutneys, cordials, and liqueurs.
