However, to throw a wrench in things. Even if you are buying frozen sheets of cake and it is frozen on site, just after baking. As long as it is handled it should be fine. Commercial freezers are SUB-freezing, usually around a negative 40-degrees. So as long as that product is handled well it will be fresh tasting once it's thawed. Provided it's handled properly.
I recently worked in a different in-store bakery. A global corporation that is mostly found in the East. AND, it was very poorly run. The manager is the single worst whiner that I have ever met and no one working there was happy, and it showed. Everyone thought is was someone elses job to clean, do inventory, organize etc. No nothing got done. The place was a STY!!
Sure, the cakes came in frozen (everything did!!), but it was the way they were handled from there that was shameful. The cases were opened and the boxes with the half-sheet sized cakes were put on the rolling rack with boxes of opened 7-inch rounds and cupcakes. On busy days the cakes were rotated quickly, but cakes like red velvet, that didn't sell as fast were sometimes opened and LEFT OPEN for the whole day out to the air. At the end of the shift the whole rack was pushed into the cooler. Great, but some of the cakes weren't used, even inside of a week. I remember putting an X on the side of a box, just to see how long it would stay on the rack. Instead of being wrapped and put back into the freezer immediately it would go from the cooler, out for a 8 hour shift, back to the cooler. Back and forth for more than two weeks. You can NOT tell me that was quality product after a day or so let alone two weeks.
Before you ask, I didn't do anything because I wasn't a cake decorator in this store. I was there for 2 days a week as the back up night baker/donut maker. So that wasn't my place. The even sadder thing is that the bakery manager was the other main cake decorator!!! She was one of the people pushing these dried out nasty cakes back and forth. This bakery also saw a LOT of complaints about poor decoration and poor cake quality. It goes to show you that a store is only as good as its management. This manager had NO clue how to deal with people, employees or customers. She always complained about her job etc. I was so glad to be rid of the place.
Anyway, grocery stores can do well with frozen product by staying on top of quality at the level they work at, but if they don't care, it really shows in the end.
.................after a very loud verbal blow out with said manager I left. After calming down I did have a sit down with the store manager and very professionally told him what was happening back there. I actually shop at that store a lot and there are a lot of new faces, but the manager is still there with three of her largest whiners. I pity the new-bies.
