Sterilize jars. Boil water in a large pot, and add jars for 5-10 minutes, then remove from the boiling water and set aside to use for jam.
Cut apricots and remove the pits. Cut larger apricots into quarters or 1/8ths. Smaller apricots can be cut into halves. Apricot skins have pectin and help the jam set, so don’t peel them.
Add the apricots, pectin, lemon juice and water into a large pot.
Bring the mixture to a low simmer over medium heat. Lower the temperature to medium low, and cover with a lid and cook on medium low heat for 20 minutes.
Remove the lid, and add the maple syrup or honey (or sugar). Use a potato masher to break up the fruit, or just stir as it breaks down naturally. Increase the heat to medium high, and bring the mixture to a rolling boil. If using pectin, boil the jam for 2-3 minutes, then turn it off. Allow to sit for 10 minutes prior to filling jam jars. If not using pectin, continue boiling the jam for 5-8 minutes over medium heat, until the jam has begun to thicken.
To ensure your jam will set, boil it until it hits 220º F. This temperature allows the sugar to dissolve. Alternately, freeze a plate prior to starting to make the jam. When it seems ready, put a spoonful on the cold plate. If it wrinkles when you touch it, it’s at the gel stage. If you tip the plate, and the jam slowly goes down the plate, it’s set. If it runs in a quick stream, it isn’t ready yet.
Use a funnel to fill the sterilized jars with hot jam.
Seal the jam jars with new lids and screw bands. Leave the jars of jam on the counter to cool and set. The jam should set in 1 day, but can take up to 2 days to set. See notes about what to do if your jam doesn’t set.
