The Best Homemade Jam Recipes

How Long Does Homemade Jam Last

Have you always fancied yourself as the type of person that makes jam at home? Or asked yourself “how long does homemade jam last?” Then read on… It’s jam season here in the UK! Between June and October every year, British fruit is at is ripest and most sweet, making it the perfect time for turning into jam.

How To Make Jam At Home

Sure you could head down to your local supermarket and pick up a pot of ready made jam, but where’s the fun in that? Making jam at home is fairly simple AND you can use your imagination to tailor your preserves to your own specific flavour palette. Like your jams more tangy and sour? Not a problem if you’re making them at home! The process of jam making is fairly similar no matter what fruit (or fruits) you end up using.

Step 1: Clean your jars. In order to create jam that is food safe, the jars that you use to store it must be totally clean in order to stop any bacteria from flourishing. This is especially true when storing jam, as bacteria loves to feed off the sugar! The easiest way to sterilise glass jars is to rinse them in hot soapy water and then put them upside down in the oven at 140 degrees Celsius until thy are dry. Make sure to remove any rubber linings that sit within the jar as these will melt or look misshapen once they emerge from the oven!

Step 2: Wash (and peel if necessary) your fruit and place it in a pan alongside jam sugar, in equal quantities. Keep it at a low heat and stir until all of the sugar has completely dissolved. If your fruit doesn’t have a lot of moisture, you may need to add some boiling water to loosen it. Keeping the mixture at a low temperature is very important, as you do not want the sugar to stick to the bottom of the pan and burn. Depending on what fruit you are using, you may need to add pectin (a thickening agent) to your mixture in order for your jam to have the right consistency to be able to set properly.

Step 3: Once all the sugar has dissolved, bring the mixture up to a rapid boil for 3-5 minutes until the jam reaches a stage where it can set. You will be able to know when to take it off the heat when you see the mixture thicken and boil more slowly.

Step 4: Test if your jam is ready to set. You can do this by taking the mixture off the heat and spooning a small bit of it onto a cold plate or saucer. Leave to cool for a few minutes and then push your finger into it. If the jam ‘wrinkles’, it’s ready to be put into jars to set! If it’s not quite there yet, just put it back onto the heat for slightly longer and keep testing it until it’s ready.

Step 5: Spoon your jam into your sterilised jars and place airtight lids on them whilst the jam is still hot. As the jam cools and sets, it will dip the seal of the jars to create a pressurised atmosphere inside. That’s why you get a distinctive ‘pop’ when you open a jam jar for the first time!

How Long Does Homemade Jam Last?

Homemade fruit preserves can last for up to year or even longer if it is unopened and stored in a cool, dry place, such as a pantry or kitchen cupboard. However the flavour and texture of your jam will start to deteriorate after around 6 months, even if you keep them tightly sealed. Once you’ve opened a jar of jam, then you will need to move it into the fridge and consume it all within 3 months ideally.

How To Make Your Jam Last Longer

  • Process your jars and jam in a hot water bath (known as canning) to reduce the risk of bacteria growing.
  • Use an equal amount of sugar to fruit in your recipe. Sugar is a preservative, so the more you use, the longer your jam will last!

It is difficult to give a definitive answer to this question, so you will have to use your best judgement and common sense when you’re deciding to eat your homemade jam. If the jam is discoloured, has visible mouldy patches or a strange smell, then it is best to leave it!
