We love these graters - in use in Rosie's kitchen for years we know how good they are. Just pop the nutmeg into the tube inside the grater, put on the lid and turn the handle. 'Great' if you have a lot of 'grating' to do! No more grated fingernails - yeuw! You can even keep spare nutmegs in the tray around the edge. We are so 'grateful' to have found these to put onto the website. Enough now.
