When preserving fruit or vegetables it is best to store them in glass jars. We get lots of products sold in jars, so if you like preserving fruit or vegetables you can recycle them by using them. Before doing so, you must make sure to sterlilize the jars, so as to destroy any bacteria which may be devloping in the jars. When you use a jar wash it well with hot water and soap and put it away.
When you decide to make your preserve wash both jars and lids again with hot water and soap and rinse them well.
In a big pan put a new, clean sponge cloth and put your jars standing up with water to cover them. Add the lids as well and bring to a boil for ten minutes.
Remove with tongs and place them on clean kitchen towels to dry before using them.
This is the old method. I don’t use this method any more but I put the clean jars and lids in the washing machine and run through a regular circle at the highest temperature.
This method has been working for me for years, but it’s up to you to chose which method you trust or like best.
