FAQs: - **How do I get a crispy exterior without using breading?** Dry the sprouts and pork well, preheat thoroughly, and cook on a raised rack. The rendered pork fat plus high airflow crisps the surfaces. - **Is there a nut-free alternative for the coating?** This recipe is naturally nut-free. For extra crunch, sprinkle crushed pork rinds or toasted sesame seeds after cooking. - **How do I know when the internal temperature is safe without a thermometer?** For safety, always verify with a thermometer. If you are stuck, cut the thickest pork cube and ensure it is opaque throughout with clear juices, but this is not as reliable as a thermometer.
