1/ Slice each cheese round in half and carefully scoop out the soft inside so only the rind is left. In a small bowl, mix the cheese with onion, half of the dill, carraway, softened butter, half of the garlic, chili powder, and black pepper to taste. 2/ Fill each hollowed-out hermelín with the cheese mixture and reassemble into 4 whole pieces. Place in a jar with a wide opening, cover with the oil, and seal the lid. Carefully shake the jar to coat the hermelin with oil. Open the jar and sprinkle in the remaining dill and garlic and the peperoncini. 3/ Reseal the jar and place in the refrigerator for 2-2 1/2 weeks. Serve sprinkled with fresh dill.
