Slice fruit in to thin slices and place in water, along with rosemary sprigs, cloves, cinnamon sticks and anise extract.
Place on burner and simmer on "low" for at least 30 minutes or as long as you desire the scent to fill your home, or until the scents start to fade.
Notes
What to do with a simmer pot when it's done:If only using the simmering pot for a short amount of time, drain the water, allow it to cool, and then store contents in the refrigerator, and then reheat it with fresh water again, when you're ready to add more scents to your home.
