If you're addicted to the no-muss, no-fuss fat-reduction finesse of cooking spray-and who can blame you?-save yourself some clams, as well as some unpronounceable preservatives and additives, by making your own.

It couldn't be easier, according to Tracey McBride, author of Frugal Luxuries: Simple Pleasures to Enhance Your Life and Comfort Your Soul (1997, Bantam). Simply combine equal parts organic vegetable oil and liquid lecithin-a natural emulsifier available at most health food stores and some drugstores-in a clean pump bottle. Slap on a label and shake the bottle well before use, and you'll never know the difference.
