In the early '60s, when I was in my first job, I would listen to an early morning BBC Scotland show 'Morning Call' in which a very Aberdonian cook, Janet Murray would give Scottish recipes and I still have the book that accompanied her talks. I still use her shortbread recipe which has the usual ingredients but instead of rubbing in the butter, melts it instead. It has always been appreciated. One that sounds revolting is 'potted heid' -ie cow's head. Don't ask! Gingerbread made with beer sounds enticing but I haven't tried it in all these years!
