I love doing this for the holidays. It makes my house smell festive and fantastic! (Without having to worry what scary things I might be subjecting my family to). You can play with this, change up the recipe, but this is what I use:
Fill a small pan about a fourth of the way with water.
1 tsp cinnamon (or a piece of whole cinnamon)
1 or 2 bay leaves
1 tsp cloves (or some whole cloves if you have them)
Then simply simmer on your stove or fireplace. Be sure to check the water level often and add more water as needed.
No ingredients you can't pronounce, and your whole house will smell amazing!
Merry Christmas to all my bloggy friends.
