Making and canning your own jam is a great way to enjoy the fruits of your labour long after the season is over. And it’s not as difficult as you might think! All you need is a bit of time, some fresh fruit, sugar and some clean jars.
Here’s a step-by-step guide to canning jam the right way.
The first step is to sterilise your jars. You can do this by boiling them in water for 10 minutes, or putting them in an oven at 160C/320F for 10 minutes.
This will help to prevent any bacteria from contaminating your jam.
Next, make your jam according to your chosen recipe. Once it’s ready, spoon it into the hot sterilised jars, making sure to leave about 1cm (1/2 inch) of headspace at the top of each jar.
Use a clean cloth to wipe any spillages from the outside of the jars before sealing them with lids.
To seal the jars properly, screw on the lids tightly and then turn them upside down for 5 minutes. This will create a vacuum seal which will keep your jam fresh for up to 12 months if stored in a cool, dark place such as a cupboard or pantry.

How Do You Seal Homemade Jam Jars?
If you’re looking to seal homemade jam jars, the process is actually quite simple. All you need is a pot of boiling water and some canning jars with lids. Start by heating up your water in the pot – it should be boiling by the time you’re ready to use it.
Next, take your clean jars and place them upside down in the boiling water for a few minutes. This will help to sterilize them. Once they’ve been in the boiling water for a few minutes, carefully remove them and set them aside to cool slightly.
Once your jars are cooled, it’s time to start filling them with your delicious jam. Leave about half an inch of headspace at the top of each jar before sealing them with their lids. To do this, simply screw on the lid until it’s tight.
Finally, return your filled and sealed jars back to the pot of boiling water and let them sit for about 10 minutes. This will help to create a vacuum seal which will keep your jam fresh for months!
Do You Seal Jam Jars While Hot?
When canning your own jams, jellies and preserves, it is important to use the proper technique to ensure a safe product. Sealing the jars while they are still hot helps to create a vacuum seal that will prevent bacteria from entering and ruining your food. If you wait too long to seal the jars, the contents may cool and form a poor seal.
Bacteria can then enter through this opening and cause the food to spoil.

Gently screw on the lid, being careful not to overtighten it.
4. Process your jars in a boiling water bath for the appropriate amount of time (consult a canning guide for specific instructions).
5. Remove the jars from the boiling water bath and set them on a towel to cool undisturbed for 24 hours .

How Do You Seal Jam Pots?
Once you have made your jam, it is important to seal the pots correctly so that the jam will last. There are two methods for sealing jam pots: with wax or with cellophane.
If you are using wax to seal your jam pots, make sure that the pot and lid are clean and dry before starting.
Melt some wax in a saucepan over a low heat. Once melted, spoon the wax around the rim of the pot, making sure that it is evenly distributed. Then place the lid on top of the pot and press down gently so that the wax seals around the edge.
Leave the pot to cool and set before storing.
If you are using cellophane to seal your jam pots, again make sure that both the pot and lid are clean and dry before starting. Cut a piece of cellophane big enough to cover the top of the pot with a little extra around the edges.
Place this over the top of the pot and secure with an elastic band or string. Make sure that there is no air trapped under the cellophane as this can cause mould to form. Store in a cool, dark place until ready to use.
