Holodets is a traditional Ukrainian meat jelly dish that is popular in Eastern European countries.
Steps:
1. In a large pot, combine pork trotters, beef knuckles, onions, carrots, bay leaves, and peppercorns. Cover with water and bring to a boil.
2. Reduce heat and simmer for several hours until the meat is tender and falling off the bones.
3. Remove the meat and bones from the broth, strain the liquid, and place the meat back into the broth.
4. Allow the mixture to cool and set in the refrigerator for a few hours until the jelly-like texture forms.
5. Serve the Holodets sliced with mustard, horseradish, and bread.
