Products you need to sterilize jars
Before you get started with sterilising your jars, there are a few products you’ll need:
- Preserving pan – a large preserving pan is the key piece of equipment needed when it comes to sterilising your jars
- Small saucepan – you’ll need a separate saucepan to sterilise your jar lids

Why do you need to sterilise jars?
When you make any kind of preservative and store it in a jar, it’s really important to make sure that there are no microorganisms or any kind of bacteria or nasty bugs inside the jars when you seal them.
If you don’t sterilise your jars properly, your preserves won’t be preserved, which defeats the whole point! Even worse, you might end up ill due to bacteria in the preserve.
So, it might seem like a bit of a hassle, but it’s well worth the extra effort.
What kind of recipes need sterilised jars?
Preservative recipes such as jam and chutney need to be stored in jars that have been sterilised.
How long do jars need to be boiled to be sterilised?
Sterilising jars in a preserving pan is quite a quick process. You’ll only need to boil them for around 15 minutes to make sure they’re free from any harmful bacteria.
Do I need to sterilise the lids?
Yes. As well as sterilising the glass jars, you’ll also need to sterilise the lids. This is an easy process and can be done by boiling them in a separate small saucepan. See below for precise instructions.
How many jars should I sterilise at one time?
As many as you can! Make plenty of your chosen preservative and make sure you have enough jars to fill. The more the better – a good chutney lasts for at least a year and you can always give some away. Homemade chutney, for example, is a fantastic gift for friends and family!
Can I just pour boiling water onto the jars?
No you can’t. Pouring boiling water onto the jars doesn’t do enough to kill potential germs. The jars need to be immersed in boiling water for a certain period of time in order to effectively sterilise them, ready to be filled with your delicious preserves.
What other ways are there to sterilise jars?
When it comes to sterilising jars, there are a few options:
In the microwave
Using a microwave to sterilise jars is an extremely fast and effective way of sterilising jars. Here’s my How to sterilise jars in the microwave guide.
In the oven
Sterilising jars in the oven is another option. Find out more with my How to sterilise jars in the oven guide.
In the dishwasher
Yes, you can even sterilise jars in the dishwasher! Read all about it in my How to sterilise jars in the dishwasher guide.
Do I need to fill them immediately after sterilizing?
The sooner the better. Fill your sterilised jars within 20 minutes, ideally while they are still warm. The longer you keep them hanging around, the more chance harmful bacteria has to get inside.
