It's very simple. Feet and ears (tails too if you have) in the pot with an onion, whole garlic, whole pepper, salt, bay leaves, carrot If you cook in the pressure cooker add enough water to cover the meat. If you cook in the stockpot you will need to add more water during cooking. In the pressure cooker cook for 2--3h. In the stockpot 6-8h, mske sure you dont end up with too much liquid - it will not coagulate. Pick meat of the bones, strain stock into glas containers, add meat to the stock and cool. Refrigerate overnight. You can add the cooked carrot to the aspic, but won't keep as well as the meat only dish.
If you like it garlicy mince some garlic and let it steep in a strainer in the stock for 15 minutes.
Next day scrape the fat if you don't like it and serve. For effect carefully flip the aspic on a cutting board before serving.
