The steak pasties made by Barnecutt's are the best I've come across. Their HQ is in Rock, just round the corner from Sharp's brewery which makes easily the best beers in the Westcountry (and which has an excellent brewery shop), though they have shops in Wadebridge, Boscastle and other places and also sell them thorough other outlets. The best way to enjoy a pasty is buy it hot and eat it immediately, even if you're not hungry. If you're near The Lizard, you should probably try Ann's Pasties, a shop in Lizard village. Her pasties are legendary but I've yet to try one.
