Pork is the un-cured meat, gammon is usually a cured ham (confusing, eh?), technically, the ham is the upper hind leg of the pig, but people refer to ham as being the cured meat that we eat cold. Bacon, on the other hand, is pork (belly or loin), that has been cured and preserved, usually using brine to preserve it - it then needs to be cooked before we eat it. This has probably confused everyone.....sorry!! Oh, and gammon is a cured leg of pork. This is all technically speaking, of course - the supermarkets call it what they like (and most of it is "formed from cuts of pork" - yuk!! K
