Haugh? Is that the same as a hock?
Soak it for an hour or so, then pour on fresh cold water, bring the ham to the boil, throw that water away, then to fresh water add parsley an onion a few peppercorns and a bay leaf. If it's been frozen or is foreign in origin salt petre will make it taste extra salty so do the above just in case
Not trying to be anti-, but since the hock isn't smoked, there's no reason at all for you to soak it. It's not going to be salty which is the only reason to soak a smoked hock...
