How To Can And Preserve Food : A Boiling Water Canner

Canning is all about preserving food by heating the container or the jar and the food to be preserved and then seal the food in the jar. Heating the food to a certain temperature kills germs. Heating the jar creates a kind of vacuum so that no bacteria can enter the jar. This preserved food can be used for months.

Equipment Needed for Canning

  1. Boiling Water Canner: This is basically a big pot large enough to cover each jar with water. It is mainly used to can fruits and pickles.
  2. Pressure Canner: This is a kind of canning container that can achieve very high pressure and temperature thus killing germs and bacteria.
  3. Canning Jars: This is normal canning jar with a lid and band that perfectly seals the jar thus preventing entry or exit of air and thus preserving the food.
  4. Lids and Bands: These are used for sealing purpose.
  5. Canning Salt: This is different from table salt and is readily available in the market. It has been used as food preservative since olden days.

  • Turn the burner up to its highest position. Heat until the water boils and steam exits strongly from the open vent port and let the steam flow.
  • Allow the canner to vent for the specified time and it will get up to pressure in few minutes.
  • Once the pressure gauge indicates that it has reached the desired pressure start timing.
  • Lift off the weight open the top and remove the jars. Let the jars cool overnight.
