Remove all the bones from the pheasant, cut the meat into cubes, and set aside a few neat strips of breast fillet.
Dice the pork belly, too.
For the marinade, combine the onions, bouquet garni, cloves, Madagascar pepper, carrots and red wine.
Marinate the pheasant in this mixture for at least 12 hours.
Preheat the oven to 180°C.
Grind the pheasant and pork, marinade included, but keep the reserved fillet strips whole.
Mix the ground meat with the coarse salt.
Line a terrine dish with a layer of fatback strips.
Arrange the pheasant fillet strips in the center.
Spoon the minced meat mixture into the terrine, pressing it down firmly.
Top with additional fatback strips.
Cover the terrine and bake for 1 hour.
Uncover and bake for a further 30 minutes.
Allow to cool completely before serving.
