Prepare everything you need. Choose a knuckle that is not too large so that baking does not take too long, but not too small so that the meat does not dry out. The optimal weight is 1-1.7 kg. Scrape the skin well with a knife, then rinse under running water and dry.
For the marinade, place Russian mustard, tomato ketchup, and salt in a small bowl.
1 tsp russian mustard, 1 tbsp ketchup, ¼ tsp salt
Add minced garlic and freshly ground pepper. Pour in soy sauce.
2-3 clove garlic, 1 pinch pepper, 40 ml soy sauce
Mix well.
Place the knuckle in a bag or baking sleeve. Add the prepared marinade.
1,3 kg pork knuckle
Tie the bag, releasing all the air from the inside. Use your hands to distribute the mixture over the knuckle, rubbing it in. Leave it in the refrigerator in this form for 6-24 hours, preferably longer. Flip it occasionally. Before baking, take it out in advance, at least two hours in advance, so that the meat warms up to room temperature.
Cook in the oven at 180 ℃ for an hour. Place the baking dish not on the top rack of the oven, but approximately in the middle, as the bag expands significantly. After the time has passed, carefully pierce and trim the top of the bag. In the next stage, which lasts half an hour, bake the knuckle in an open form, periodically pouring the rendered fat from the top.
Properly cooked meat should have a golden crust and easily separate from the bones. The knuckle can be served both as a hot meat dish and as a cold appetizer.
