Boiling Gammon and making Pea & Ham soup from the stock

How to boil up a lovely bit of gammon and make delicious pea and ham soup from the resultant stock A word of caution about gammon. I had a mate who worked in an abattoir (slaughterhouse), and he said the one thing he would under no circumstances eat again was the "formed" gammon they sell in supermarkets - it's scraps rolled together in a ball and made to look like "gammon". It's disgusting and nothing like the real thing. I get mine from Dave, the egg and cheese guy at Tewkesbury market. He slices it up and packs it himself and it's excellent, real and cheap. I get eggs and cheese from him too - just compare the prices and the quality. Dunno what happened to my mate who worked in the abattoir - last I heard he and his Mrs were living on a boat and he was washing down 747s at Heathrow for a living!
