Simple Apple Cider

I wasn't sure if this was worth a post, but I had to look up Apple Cider recipes for Thanksgiving and they were all unnecessarily complicated.  I like the way my experiment turned out, so here it is.  You need a crockpot for this recipe.

1 gallon of Apple Juice
2 Tbsp ground cinnamon (cinnamon sticks would also work)
1 Tbsp vanilla

Combine all of this into a crockpot and heat.  Serve when warm.  It also smells delicious.
