Did you hear the one about the ultraglamorous costume designer who was born around here, now lives in New York, and times all her flights home so she can throw her Vuitton into the rental car and swing past Mel-O-Glaze to pick up a dozen before they close? That's it, no punch line, just sweet, cakey, and (you saw this one coming) mellowly glazed doughnuts. French Twists. Chocolate glazed. Squishy jelly-filled. Crisp apple fritters. Even tasty low-fat jam bars. For domesticated-animal enthusiasts, Mel-O-Glaze recently debuted a line of dog biscuits (fireman, policeman, mailman, dogcatcher), and, for cats, catnip-dusted cookie-rats.
