Traditional French country terrine: coarsely ground pork shoulder, pork belly, and chicken livers seasoned with cognac, garlic, shallots, thyme, and allspice, baked in a water bath and chilled.
Combine pork shoulder, pork belly, chicken livers, shallot, garlic, Cognac, egg, thyme, allspice, salt, and black pepper. Mix thoroughly until cohesive.
Line a ceramic terrine dish with strips of bacon or fat. Pack meat mixture firmly into the dish, smoothing the top.
Cover with lid or foil. Place in a roasting tin with hot water coming halfway up sides. Bake at 160°C for 1.5 hours until juices run clear (72°C internal).
Place a weight on top and cool completely. Refrigerate for 48 hours to develop mature country flavor. Serve sliced with cornichons and baguette.
