Put the meat in a pan of water with the vegetables and let cook gently for about 2 hours. The meat needs to be cooked. Turn the egg yolks and oil into a mayonnaise, then add the other ingredients. Put this in the food processor, everything is nicely purled. Cut meat into thinning slices and place a layer of slices on a bowl. Put a layer of sauce over it and then meat again. Do this until the meat is finished and end with a layer of sauce. Sprinkle with the capers. Let stand for a night, the flavors will go through well.
