When I was growing up my mom would make "Christmas Scent." It's awesome and here's the recipe:
3 (4-in) cinnamon sticks
3 bay leaves
1/4 cup whole cloves (1 small bottle)
1/2 Lemon, halved
1/2 orange, halved
1 qt water
Combine all ingredients in a saucepan that is old and you don't mind it getting stained. Bring to a boil, reduce heat, and simmer as long as desired. After a few hours and may start to look a little ugly, but you can just continue to add water. After a few days you may want to remake it.
This is my favorite and for those coming over on Sunday, I hope that you will enjoy it also!
