Hash Browns

I think I finally have the secret to hash browns. I baked several potatoes at 350F for an hour or so. They chilled in the fridge for about a day. Then, I grated them and placed them on cookie sheets which had been sprayed w/spray-cooking oil. I also sprayed the top liberally with the same oil sprayer. That went into the oven at 450F for maybe half an hour or so? This stage required watching fairly carefully. When the bottom starts looking suspicious like it's about to burn, you take them out and flip them. You don't have to bake them again, provided they were not spread to thick to begin with. Anyhow, it worked. This will be the method to my madness now. Besides, Edwin loves them!
