I was a graveyard cook at Denny's while putting myself through college and used to have to "prep" hashbrowns for the dayshift everyday. Prep consisted of opening the box, adding hotwater, then moving to the walk in cooler. They were fully rehydrated and ready to cook after about an hour.
Thanks for confirming,
Ooompa Loompa. I can't believe it took me this long to figure this out. I always thought they used frozen, as that's what almost all restaurants use, and that dehydrated were backpacker sustenance. I tried every frozen brand, the refrigerated types, and every possible way from scratch. Nothing came close to that perfect texture and crispiness of Dennys. I must say though, while I find Dennys in California/west coast overall to be very consistent for breakfast, several of their locations in other states have been hit or miss. 2 locations in Amarillo recently sampled were horrid.
