Looking to go green this Thanksgiving? For this Treasure Tuesday, we suggest switching out your kitchen aid for a good-old Dover Egg Beater! Dover was originally a brand name but quickly came to mean any beater of this type. On this egg beater, the wider strips of metal rotate but the thin loop in the center does not. These were first patented in the 1870s and, at the time, were a huge time and energy saver!
