Paul, I think that would be a good idea for an occassional goodie. Otherwise, I suppose it could (potentially) pose a problem for some. (Extremes, of course.) I have to laugh though, because I did something similar to your suggestion. When I was REALLY in "diet mode", on Atkins, I wouldn't
dream of eating a piece of pizza. So, when plating some for my teens, I stood over the pizza box, mouth opened, and inhaled slowly so I could "taste" it.

Heck, it worked!
