Our slow cookers are probably the most used appliances in our house!
We do a lot of hiking and nothing beats coming home knowing that dinner is ready and smelling fabulous!
Use this website a lot and have found just about everything on it:

I have a slow cooker hot apple cider recipe that I've been using for years. Actually have made it outside on a campfire and in a pot on the stove, but the best is in the slow cooker - again because the house smells soooooo good when you come back after a long cold (we live in Northern Ontario) winter day hiking or skiing.

1 quart cider or apple juice (I've used both)
1/2 cup brown sugar
1/2 tsp. whole cloves
1 small cinnamon stick
1/8 tsp salt

Simmer over low heat at least 1 hour (better for 4 + hours)

Recipe can be tripled, quadrupled, etc.

Enjoy!
