Here's what you do:
Bring a small saucepan filled with water to a boil (more if you want it to last longer, keep adding if it goes down, which it will), add in your desired ingredients, let it boil for about five more minutes, then turn to simmer and go on about your business. You'll be smelling the sweet scent in no time and won't even have to burn a candle. My husband smelled it the other day and asked if I was making something special. He was a little disappointed when he discovered he couldn't eat it. If you want more recipes, Apartment Therapy has some great options for you as well.
