Cut the apricots in half, take the pit out, and cut each half into slices.
Put the sugar over the apricots and leave them in the fridge overnight.
The next day you will notice that they have left a lot of juice.
Put them in a large pot and squeeze the lemon juice on top.
Set the heat to medium, and put the pot on the stovetop.
Clear the foam that forms on the top as the apricots are boiling – this is formed by the impurities in the sugar and can affect the canning process.
Mix frequently as the apricots tend to stick to the bottom of the pot, especially towards the last minutes of boiling.
Boil until the apricots change colour to a beautiful bright orange, and the consistency of the mixture is jammy-like. This takes around 15-20 minutes.
To test if the jam is ready, pour a tablespoon on a small plate. If you can run your finger through it and leave a clean mark, it’s ready.
Turn the heat off.
Meanwhile, sterilise the jars.
Wash the jars and their lids very well, with soap and water. Rinse well to remove all the dish soap.
Put the clean jars and lids in the oven on a metal tray and turn the heat on to 150 degrees Celsius.
Let them dry in the oven for 10 minutes.
Take them out carefully, as they will be hot.
To prevent cracking, make sure the jars are on a metal surface, such as the tray or stainless steel knives.
Pour the apricot jam in each jar up to the top line, and close the lid.
Place the jars upside down and leave them to cool down slowly.
Once they are cold, place them in your pantry for winter.
