Abstract: A method and apparati for preparing and displaying a donut having a "fresh-baked" quality in a retail environment principally uses standard equipment available in a typical convenience store or quick-service restaurant. The method utilizes pre-frozen donuts manufactured at a centralized manufacturing facility and involves thawing, storing and heating the frozen donuts at the point-of-service. The donuts are thawed under refrigeration but in a generally humidity-constant environment. This on-site procedure allows a retailer to quickly and conveniently produce a moist, fresh-tasting donut with minimum equipment and effort. Furthermore, the present production method allows the retailer to control the number and type of donuts produced for sale, thereby substantially eliminating waste and allowing the retailer to immediately tailor donut production to local consumer demand. An improved applicator eases the glazing process to permit relatively inexperienced personnel to properly glaze the donuts.
