Chicken livers have a mild flavour and soft creaminess. Take care not to overcook a terrine—this one should be moist and juicy, with the bacon wrapping adding a contrast of flavour and texture.
Heat the butter in a pan, add the shallot and heat through for 2 minutes. Remove from the heat, add the livers and pork and stir over very low heat for 3 minutes, or until the meat and liver are warm. Mix in the brandy, port and five-spice, season well and cover with plastic wrap. Cool slightly, then refrigerate overnight.
