Marinate the pork knuckle. Place the knuckle in a cooking pot. Add chopped onion and carrot to the meat. Add peeled garlic, cumin and 5-6 peppercorns. Salt and pour in the soy sauce. Finally, pour in the beer, it should completely cover the meat, so choose the volume of the pot so as to use a minimum of the foamy drink. Cover the pot with a lid and put it in the refrigerator overnight to marinate, so that the taste of the dish becomes brighter and richer. However, you can cook the knuckle as soon as you pour the beer over it.
Boil the knuckle. Place the pan on high heat and bring to a boil. Skim off the foam from the boiling beer and reduce the stove power to minimum. Boil the knuckle under the lid for approximately 120 minutes. Turn over once during the cooking time. After 2 hours, remove the knuckle and let it cool slightly.
Make the sauce. Combine honey and mustard in a deep container. Mix everything thoroughly and let it sit for 5-7 minutes.
Prepare the knuckle for baking. Cover the baking sheet with foil. Remove the vegetables from the pan in which the knuckle was cooked and distribute them on the baking sheet. Place the apples on top of the vegetables. Pour 2-3 ladles of beer broth on the apples. The bottom of the baking sheet should be covered with liquid. Grease the knuckle generously with honey-mustard sauce on all sides and place it in the center of the baking sheet. Place the potatoes around the knuckle. Place the sauerkraut in the corners of the baking sheet.
Bake the Bavarian knuckle in the oven. Place the baking tray with the knuckle in the oven preheated to 170 degrees. Bake for 40 minutes until golden brown. Every 10 minutes, pour the beer broth from the pan over the vegetables and meat. If necessary, brush the meat with the remaining sauce.
