These were made by my grandmother while I was growing up. Whenever she made them, some always made their way to our house. She would make them in the morning and put them on a platter and into the refrigerator they went until suppertime--probably to tighten up. I remember seeing them sitting there with waxed paper over them. These are so good if you mash them a little on your plate and put butter and salt on them. It is a way to use up leftover rice which is what Grammie did. She didn't throw anything away. She even saved all her leftover meat whether it be one hamburg patty, or a hotdog, or a roast and would grind them up at the end of the week and used the following recipe but with meat instead of rice. She would add some chopped onion to the meat. She didn't waste anything. The rice is held together with an egg and white sauce. Grammie never measured so this is about what I use to make mine. The time listed is if you keep them in the refrigerator for a few hours, but you could have them sit only about an hour or so.
