Joining Jay and James this week is Mr Truffle, one of Britain's leading truffle experts and the perfect person to explain the dodgy, delightful and delicious business of truffles.  From spending 60k on a single white truffle to trading thousands on them in nighttime car park deals, where to find them in the forest to the right time to hunt them , it's an amazing trip inside this hidden world.  Plus two famous ladies join the Dream Dinner Party, one with the most amazing table you'll ever encounter.
