Cover the form with terrine with foil around the edges, put it in a container filled with water. There should be enough water to fill half of the form with terrine. To do this, you can use a deep frying pan or any heat-resistant cookware. Cook at a temperature of 210 degrees for 2-2. 5 hours to check the readiness with a wooden skewer. If the transparent juice and the contents lag behind the walls of the mold, then the terrine is ready. Remove the foil, let the resulting juice drain. Cool. Cover the container with foil again. Put the oppression on top and leave in a cold place for at least 12 hours. Remove the oppression, form it, turn it over, cut the terrine into slices.
