Add brown sugar, spices, and herbs. Stir and incorporate.
Add the cider and the rum. Don't forget you did this for later on when you're asking why is the rum gone.
Cook until reduced slightly and it becomes syrupy.
Notes
I like to season my chops with dried thyme, as well. Just sayin'.
You can peel the apples and dice them into uniform shapes if you could spend all day in the kitchen and you're trying to impress your significant other or something.
But here, ain't nobody got time for dat. So I just cut them so they're generally the same size and I left the skin on. I know, I'm a monster. Culinary school me would have cursed today me out.
I didn't have cloves at the time but I'm sure it would've been awesome.
