My mom gave these Misto things out for Christmas. Have you seen these? They are intended for use instead of store bought oil sprayers. You fill it half way up with the oil of your choice, give it a few pumps and spray. This allows more control over what you are eating and less impact on the environment.
I am also thinking of other uses: citronella oil and water mix for bug spray in the summer or lavender (or lemon, or mint, or whatever your favorite is) and water for air or fabric freshener. And of course, they make a great gift, especially for the foodie in your life.
What do you think? Do you have one? Do you have more ideas for uses?
