do this and you will thank me.

1. get a tea kettle
2. fill half way or two-thirds full of water
3. add a cinnamon stick or two
4. add 7-10 cloves
5. throw in an orange peel if you feel like it
6. turn your burner on low heat
7. enjoy the new aroma that fills your house
8. periodically check to make sure all the water hasn't evaporated from the kettle, leaving a nice burning effect in the bottom of said kettle
9. fill with more water and continue
10. thank me

post script: don't use your Le Creuset kettle. use an el cheapo one that you don't care about, because you will inevitably fail instruction #8 at some point. it's okay when you do, but you will never get rid of the charred ingredients in the bottom of your kettle. (and don't worry, when this happens, it does NOT mean that your house is on fire, even though it might smell like it.)
