Canned & Jams
Preserving fruits and vegetables is the best way to keep a reserve of out of season produces. You can be sure that no preservatives are added. It doesn't happen often that my trees overproduce, but I sometimes get some extra fruits from my neighbours. When the production of seasonal fruits is at their peak you can find crates of peaches and apricots at a very reasonable price.
