Rinse the pork hocks, beef shanks, and pig’s feet and ears thoroughly to remove any debris.
Place the meat and bones into a large pot and cover them completely with water. Bring the water to a boil, then reduce the heat to a gentle simmer. Skim any foam or impurities that rise to the top during the first 20 minutes of cooking to ensure a clear broth. Season with salt.
Let the meat simmer on low heat for at least 5 to 6 hours. Once your broth has developed a rich, meaty flavor, strain the liquid into a large bowl, separating it from the bones and meat.
Allow the meat to cool slightly, then shred it into bite-sized pieces. Discard any bones or excess fat, and place the shredded meat into a shallow dish. Using a small fork or something long and thin, like a toothpick, scoop out bone marrow out of the bones and add to the shredded meat.
Pour the strained broth over the meat until it’s completely covered. Add grated garlic to the broth and meat, and carefully mix it in. Add boiled egg slices if you desire to add an egg for extra protein to your meat jello. Let the dish cool to room temperature before transferring it to the refrigerator. Chill the holodets for at least 4 hours, or until it has solidified into a firm, jello-like consistency.
Once your holodets has fully set, you can carefully scrape off the fat that rose to the top. I like leaving it as is, for added fat, to my meal. Then, slice meat jello into portions and enjoy.
