Simply oranges and cloves. Boil and breathe.
This is my favorite scent. It calms me and makes it OK to be in the kitchen, even if I have a big old sink full of endless dishes from Sunday dinner.
Sometimes I sprinkle in a generous teaspoon of ground cloves too - just to make it even better. This is the best aroma therapy for me. (Careful not to let the pan boil dry. Burnt cloves...not so much.)
