From what I have tasted, head cheese isn't a sort of brawn. It is brawn.

I'm not much fussed if people say "different to" or "different from" but, personally, I always try to use "different from".

As an aside to people saying drawer when they mean draw: I always say draw but, when I was an apprentice, it was pointed out that there was no "r" in the middle of the word "drawing". Since then, I have made a conscious effort not to say "drawring" but, even after these many years, it doesn't come naturally.
