APPLE BUTTER!!!
It’s amazing. Chop up washed apples (no need to peel), put in slow cooker with cinnamon (and sugar if they’re tart). Leave for hours and hours. Puree with hand blender in the pot.
You can stop here and keep it as apple sauce, freezes beautifully.
But don’t do that. Take the lid off the slow cooker and let it cook on. Again, for hours. It will get darker, thicker and sweeter. Stop whenever you get to the texture/sweetness you like. Put in jars or freeze.
You can use it for everything, hot or cold; on top of yoghurt, base for crumble/tart/pie, stir into porridge, spread like jam, in baking to reduce sugar. It’s amazing.
And it turns about 1kg of apples into one large jar!
Tons of recipes online. Tip; only add sugar to taste at the end for the last hour or so; the long cooking allows the sugars in the fruit to come out so it gets sweeter/more intense as it goes on
