The 'Lancashire Evening Post' - Wednesday 27 July 1932 - has; "What are tosset cakes. Granny?” Well, tosset cakes is same as Goosnargh cakes, Garstang Fair cakes, Stalmine Club Cakes, and Pilling Cakes. They’re all the same, but different sizes and different names. Butter and sugar and flour, with spices and seeds, and not too much cooking, that’s all they were and very good and wholesome they were, too, I can tell you.”
