One day before the roasting, rub the pork belly with about 4 tbsp. oil, 1 tsp. salt, pepper, 1 tsp. grated caraway and 4 crushed garlic cloves (rub all sides). The garlic should be pressed and not cut. This way the meat can absorb the taste better. Similarly with the caraway seeds: grated caraway is absorbed better by the pork.
