How to Properly Sterilize Jars for Preserving
The process of Sterilizing Jars for Preserving in boiling water is rather easy. It takes about 15 minutes.
- Wash jars in hot soapy water and rinse in hot water. You can also do this in the dishwasher. Put jars in a deep, large pot and cover with hot water.
- Cover pot and bring water to a boil and boil jars for 15 minutes from the time steam emerges from pot. Turn off heat and let jars stand in hot water until ready to use. You can leave them for up to an hour.
- Just before filling them with jam or other canned goods, take them out of the water one at a time with heat-resistant tongs and then invert jars onto a kitchen towel to dry. (You should fill jars while still hot.)

In addition to sterilizing the jar, you also need to sterilize the lids you place on the jars.
- Place canning lids in boiling water for 5 minutes to sterilize. Keep warm until ready to use.
