Step 1

Put a small plate in the freezer. Tip the chopped apple and caster sugar into a large saucepan along with 350ml of water and bring to a simmer, stirring to dissolve the sugar.

Step 2

Cook gently, stirring regularly, for 30 mins until the apples have collapsed.

Step 3

Stir in the lemon juice, add the cinnamon stick and simmer gently for another 2-3 mins until the mixture is thick and glossy.

Step 4

Remove the small plate from the freezer and drop a little of the mix onto it. Leave for a few seconds – it should be fairly firm. If it’s still a little runny, put the pan back of the heat and simmer for another 10-15 mins. Put the plate back in the freezer and test again, it should now be ready.

Step 5

Divide between clean, sterilised jars and seal. Will keep for three months in a cool, dry place. Once opened, chill and use within one month.
