"Dundee Cake will last approx 3-6 months when stored in an air tight cake storage tin (if you can wait that long grin )"

Pretty good suggestion. I think I'm going to try making one of these cakes every 4-6 months and storing it in a cake tin.

I like several of the other suggestions above as well. I'm curious about the "parched corn". Was this just corn kernels that were dried and then ground? Or did you bake it in the oven at a low temp??
