Friend of a friend runs a farm in Umbria... We go to said friend's family every Christmas breakfast (they're like growing up together friends, my mum was friends with his, we're the same age, mums still live in same area sort of thing). Anyway, Umbria guy did breakfast once, smoked salmon, scrambled eggs and... loads of white truffle. Been trying to find out ways of blagging them cheap since, though never succeeded. Should make friends with more Italian farmers I suppose.
