Did you ever try making glögg julskinka?
(I do speak swedish, but don't have a Swedish keyboard, and most people find Swedish written without the Swedish letters rather annoying:) )
So, have been making pepsi ham for the last couple of years (so tasty, but I've done it enough times now, for the record, always use pepsi, it makes a better one that if cooked in Coca Cola).
So my thoughts was that Swedish Glogg should give a similar effect to Pepsi, as the Swedish Glogg is quite sweet and the spices could add an interesting flavour. But of course it could go the other way.
My thinking was that I'll cook the gammon (uncooked ham) for the set number of hours in glogg, adding some pepper, onion, bay leves. Thinking I might exchange the onion for a orange or possibly add rasins or something. Also possibly use some Chartreuse but not certain
