Peel, and core the apples then chop into bite-sized pieces.
Place in a large saucepan with 3/4 cup water and bring to the boil. Reduce heat to a simmer and leave for 15 - 20 minutes or until the apples have softened.
Remove from the heat and pour the apples into a colander to drain off the liquid. Push down on the apples with the back of a spoon to push out any excess water.
Tip the apples into a blender and blend on high until a smooth purée forms. This will take a couple of minutes max.
Pour the purée back into the saucepan, then add in the honey and lemon juice. Place back on the stove over a low heat and allow to simmer until the mixture is thick enough to stand a wooden spoon in it without it falling. This was 1 hour and 15 minutes for me. It may be more or less for you. Be guided by the thickness of the purée, not the time.
Once thick enough, transfer the paste into a container that's been lined with baking paper. Allow to cool slightly then put on a lid and place in the fridge to firm up overnight.
Remove the apple and honey paste from the fridge and chop it into any shapes you like. You can leave the paste in this container though I like to add another piece of baking paper on top before putting the lid back on to ensure it doesn't dry out.
I've kept these pastes in the fridge for as long as 12 months, but in most cases they get eaten well before that!
