Pour boiling water into a larger mold, put it in a form with terrine, covered with foil. Cook in a preheated 180* oven for 1 hour.
Put the cooled terrine on a large plate, without removing the mold, and refrigerate for 10-12 hours. After 12 hours, remove the mold, strain, cut into slices 1 cm thick.
Happy and delicious holidays to you!
