LOL!

My mother was one of the worst cooks I've ever suffered under, she could burn water!
Yes that is definitely a Scottish thing Ed, as is deep-frying just about anything, and in the past, I think everything would have been fried in 'beef dripping' (far less so today). Even in England though, I think vegetable oils only began to be widely used in the 1960's. In West Yorkshire, where I live now, some fish and chip shops still cling onto using beef fat for frying, even more so in North Yorkshire, but in South Yorkshire, where I was born, it is only very rarely encountered. Personally, I find the fat tends to permeate and coat the food, giving a flavour and texture I dislike. Thanks for the Lambsfoot content my friend
I'll be off to the market early in the morning, but I'll be carrying my regular with me
