This sterling piece is a variation of the toast-rack. Made by Patrick Robertson, Edinburgh, 1773. Currently resides in the Royal Scottish Museum in Edinburgh.
This piece derives it's name from the food that it held. What is it called ?
You have the right idea. The item we are looking for was originally defined as "flat roundish unleavened cakes of oatmeal or barley-meal". I believe the word is Scottish in origin.
