I have been using carmel glaze in one of my single screens for about 3 years now, I have a smaller popper dedicated to just that. I would not ever use glaze in my main popper. Profit margine is a lot lower than regular popcorn, but also warrants a higher retail price. I sell more to older patrons than I do younger (have not tried the other flavors available because of space--I am sure the blue raspberry would sell to younger). It has not taken away from regular popcorn sales, but has not added much to the per cap either. I keep it more for giving another choice to my customers.
