Drizzle the olive oil on the pork 1 tablespoon at a time and massage it into the scoring. Then, taking 2-3 generous handfuls of sea salt flakes and press it into the rind ensuring you have a visible layer of salt on the rind. Ensure you have a roasting tray with a roasting rack large enough for your pork. Cut your fennel branches in half, then lay them on the roasting rack making a bed for your pork, and transfer the pork to the tray. Into the bottom of the tray pour 2 cups wine and 1 cup water.
