From The Devil's Food Dictionary: (This was too good not to share!!)
A fatty substance, actually a steroid, important to human health. Home cooks will be pleased to know that adding cholesterol is a handy shortcut for improving flavor and mouthfeel in dishes ranging from BBQ ribs to layer cake. A heaping tablespoon per serving should suffice for most recipes and can either be incorprated into the dish or served on the side. Try wrapping a spoonful or two of cholesterol in a lettuce leaf, or substituting it in any recipe that calls for celery seed.
