Soak the trotters, hock and beef in cold water for 2 hours, then scrape the skin clean with a knife.
Put the meat in a large pot, cover with 2.5 l of cold water, bring to a boil and skim off the foam.
Simmer on the lowest heat, partly covered, for 5 hours; add the onion, carrot, bay leaves and peppercorns for the last hour and the salt 30 minutes before the end.
Lift out the meat and strain the broth through a fine sieve; about 1.2 l should remain. Discard the onion, bay leaves and peppercorns.
When the meat is cool enough to handle, remove the bones and cut the meat, skin and soft tendons into small pieces.
Spread the meat in shallow dishes, add a few slices of the cooked carrot, stir the crushed garlic into the warm broth and pour it over the meat.
Cool, then refrigerate for at least 8 hours until set firm. Serve cold, cut into squares, with mustard or horseradish.
