Depends where in the UK you are. I guess fish patties prevalent, but in East Yorkshire potato patties with sage are also common. They're really delicious! You're probably right that cows are not killed mainly for their tallow. Yet, let me try to illustrate why this can be off putting anyway (not trying to flame troll, but just to politely answer your comment): If your cat (or dog, or horse, etc) died in a traffic accident, would you cook a meal from it, even if it was not killed for that purpose? Some people respect the rights of all animals to the degree that they refuse to consider them as food; just like we do with our animal pets and other humans (even the humans we don't like, if any).
