Make jars of apple jam and give them as gifts to friends and family. It’s great spread on toast or used as a filling in your favorite cakes and baked goods.
Place a small dish in the freezer to keep it cool. Place the diced apple, caster sugar, and 350ml water in a large saucepan and bring to a boil, stirring to dissolve the sugar.
Cook for 30 minutes, stirring occasionally, until the apples have collapsed.
Stir in the lemon juice, then add the cinnamon stick and continue to cook for another 2-3 minutes, or until the sauce has thickened and become glossy.
Take the tiny dish out of the freezer and place a small amount of the mixture on it. Allow a few seconds for the mixture to firm up. If it’s still a bit runny, reduce the heat to low and continue to cook for another 10-15 minutes. Return the plate to the freezer and test it one again; it should now be ready.
