Canning and preserving food allows you to enjoy seasonal produce like fruits, vegetables, and meats all year round. Here are some tips on the main techniques for safe and effective food preservation:


Canning involves placing food in sterilized jars and heating them to a temperature that destroys microorganisms and inactivates enzymes. This prevents spoilage. Follow these steps:

  • Select fresh, blemish-free produce. Wash and prepare it - peel, slice, dice etc.
  • Use proper canning equipment like a water bath canner or pressure canner. Sterilize jars and two-piece caps in boiling water beforehand.
  • Pack food into jars, leaving 1⁄2 to 1-inch headspace. Remove air bubbles and wipe rims clean before sealing jars.
  • Process jars in a water bath or pressure canner according to recipe directions for the appropriate time to achieve a full seal.
  • After cooling for 12-24 hours, check seals are concave and secure. Label jars with contents and date. Store in a cool, dark place.


Pickling preserves food like vegetables, fruits and eggs in a brine solution. Steps include:

  • Prepare a brine of water, vinegar, salt and other aromatics like sugar, spices. Bring to a boil and simmer.
  • Pack washed produce into sterilized jars and pour over hot brine, covering completely. Leave 1⁄2 inch headspace.
  • Seal jars and process in a water bath canner based on recipe timings to seal jars.
  • Pickles can be enjoyed immediately but also gain more flavor with 2-3 weeks of refrigeration.


Many fruits and vegetables can be frozen raw or cooked. To freeze properly:

  • Blanch vegetables in boiling water briefly to deactivate enzymes.
  • Pack food in airtight containers or freezer bags, removing excess air.
  • Label with contents and dates. Freeze at 0°F or below.
  • Most foods last 8-12 months in the freezer. Defrost in the refrigerator before use.
