Thought Co. is one of my go to sights for a wide range of ideas. The Mabon Cooking post from Thought Co. includes links to: crockpot apple butter, herb butter blends , and there are more recipes there too!
A note on herb butters: if you want it to remain spreadable, whip olive oil or another light oil of your choosing into it AND diary free diets can use margarine or other substitutes in the same quantities to create the mixtures.
