If someone has already mentioned this, I missed it.
The Italians have a way with trotters, it is called ZAMPONE. As I understand it, basicaly a stuffed pigs trotter. I have never had it, but I believe it is very much like cotechino (delicious with lentils) which is a coarse grained sausage, up to 50% fat, normally boiled/simmered with the lentils (a winter dish).
Do not know where you can get a reipe now, but you could try searching the net.
