Making Apple Butter is very similar to making applesauce. You cook down the apples
But here is where it changes. You put the sauce into your crockpot and add sugar, cinnamon, nutmeg and cloves. Stir and set the timer on low for 4-5 hours.
Be sure to put the lid on, but not all the way. The lid is on to keep the splatter down and it is cracked open to allow any liquid to evaporate, which is what will make it thick and turn into apple butter.
You can see how the color changes to an almost caramel and how it thickens.
