To store leftover scrapple, allow it to cool to room temperature. Then, place it in an airtight container or wrap it tightly in plastic wrap. Store it in the refrigerator for up to 3-4 days.
Freezing:
If you want to freeze scrapple for longer storage, wrap individual slices or portions in plastic wrap or aluminum foil. Place them in an airtight container or a freezer bag, and label with the date. Scrapple can be frozen for up to 2-3 months.
Reheating:
To reheat refrigerated scrapple, you can simply pan-fry it in a skillet with a little oil until it's heated through and crispy on both sides.
If reheating frozen scrapple, allow it to thaw in the refrigerator overnight. Then, reheat it by pan-frying as mentioned above or by using the air fryer at 350°F (175°C) for 5-7 minutes, flipping once during cooking.
