UK gardeners can preserve surplus fruit and vegetables using seven main methods: bottling in Kilner jars, dehydrating, making fruit leather, salting, oil preserving, sugar preserving, and vacuum packing. Water bath canning reaches 100C and suits high-acid foods like tomatoes, fruit, and pickles. Low-acid vegetables require pressure canning at 116C to prevent botulism. Properly bottled fruit lasts 12-18 months. Dehydrated produce stores for 6-12 months in airtight containers.
Key takeaways
- Water bath canning at 100C is safe for high-acid foods like fruit, tomatoes, and pickles
- Low-acid vegetables need pressure canning at 116C to destroy botulism spores
- Properly bottled fruit in Kilner jars lasts 12-18 months at room temperature
- Dehydrating at 55-60C removes 80-90% of moisture and stores produce for 6-12 months
- Fruit leather made from 500g of pureed fruit dries in 8-12 hours and keeps for 3 months
- Salt preserving uses 60-80g of salt per kilogram of vegetables and costs under ten pounds to start
