“ But when paste is to be boiled, suet will make it much lighter and finer than butter.Apple dumplings may be made in a very plain manner with potato paste, and boiled without cloths, dredging the outside of each dumpling with flour. They should boil about three quarters of an hour when without cloths.The apples for dumplings should always be whole, (except the cores;) for if quartered, the pieces will separate in boiling and break through the crust. The apples should never be sweet ones. ”
